Hi there! I understand you're seeing a white screen and then the Acellus app closes on your Kindle Fire with Android 9. Let's work through this together.

First, I'd like to confirm a couple of things:
- Is your Acellus app updated to the latest version from the Amazon Appstore?
- Have you noticed whether the white screen happens immediately on opening the app or after some loading?
- Have you tried restarting your Kindle Fire since this issue started?
- Are other apps working fine on your Kindle, or is this issue isolated to Acellus?

In the meantime, here’s a step-by-step approach we can try:

1. Restart Your Kindle Fire: Hold down the power button for about 40 seconds until the device powers off. Then press the power button again to turn it back on. This soft reset can clear temporary system glitches.

2. Update Acellus App: Open the Amazon Appstore, go to "My Apps & Games," and check if there’s an update available for Acellus. Running the latest app version ensures compatibility and bug fixes.

3. Update Android System WebView: The Acellus app uses Android System WebView for displaying content. If it’s outdated, it may cause white screens. Although Kindle Fire's Amazon Appstore may not show Android System WebView explicitly, check for any system updates on your Kindle Fire settings and install if available.

4. Clear App Cache and Data:
- Go to Settings > Apps & Notifications > See all apps > find Acellus.
- Tap on it, then tap Storage & Cache.
- Tap Clear Cache first, and then Clear Data. This will reset the app without uninstalling it.

5. Reinstall Acellus App: If the above doesn’t help, uninstall the Acellus app, then reinstall it fresh from the Amazon Appstore.

Let me know which steps you've tried or if you see any error messages during this process. From there, we can dig deeper or explore alternate solutions.

Are you satisfied with this initial solution?

I’m so glad reinstalling the Acellus app got it working for you! That’s often a straightforward way to clear out any corrupted files or settings causing issues.

If you ever face similar problems in the future or want a quick refresher on troubleshooting the Acellus app, here’s a concise set of steps that usually help resolve common issues:

1. Restart the device to clear temporary glitches.
2. Check for app updates in the Amazon Appstore to ensure compatibility and bug fixes.
3. Clear app cache and data from Settings to reset corrupted temporary files without uninstalling.
4. Reinstall the app to replace damaged files or problematic configurations.
5. Ensure stable internet connection since Acellus requires reliable connectivity.

It isn't working again!

Thanks for letting me know it’s acting up again. Let’s try to get this fixed so you can keep using Acellus smoothly on your Kindle Fire.

Since reinstalling helped briefly but the problem returned, here are some additional focused steps:

1. Check for System Updates: Go to Settings > Device Options > System Updates on your Kindle Fire. Install any available updates. An updated OS ensures better app compatibility.

2. Update Android System WebView or Equivalent: Acellus relies on this for rendering content. Kindle Fire devices don’t always allow direct updates of WebView via Amazon Store, but system updates can help here.

3. Verify Network Connection: A slow or unstable internet connection might cause the white screen issue. Try switching between Wi-Fi networks or test with mobile hotspot if possible.

4. Limit Background Apps: Close other apps to free system resources. Sometimes low memory can cause apps to crash.

5. Run Acellus in Airplane Mode with Wi-Fi Off, then On: Sometimes temporarily disconnecting and reconnecting the internet clears connectivity glitches.

6. Create a New User Profile in Acellus App: Sometimes user profile corruption causes issues. Logging in with a new user profile might help isolate that.

7. Check Acellus Server Status: Occasionally, Acellus’s servers may experience downtime. You can check their technical support page for announcements here: Acellus Technical Support 1.

8. Contact Acellus Support Directly: If none of these steps help, you might want to contact Acellus support for account-specific or device-specific troubleshooting. Their contact info is here: Acellus Contact Us 8.

Please let me know which of these steps you've already tried or if you want me to guide you through any specific step in detail. Also, do you see the white screen immediately after opening, or does the app load a bit first?

Hi! I see you’re experiencing the Acellus app showing a white screen and then closing on your Kindle Fire. This is a known kind of issue that can sometimes be due to app glitches, outdated software, or device-related problems. Let’s work through some tailored steps to get you back on track:

1. Restart your Kindle Fire fully: Press and hold the power button for about 40 seconds until the device turns off. Then power it back on. This can clear temporary glitches causing the white screen 2.

2. Ensure Acellus app is updated: Open Amazon Appstore, go to "My Apps," and check for any Acellus updates. Running the latest version helps avoid compatibility issues 1.

3. Clear Acellus app cache and data: Go to Settings > Apps & Notifications > See all apps > Acellus > Storage & Cache > tap Clear Cache then Clear Data. This helps remove corrupted temporary data.

Hi! I see the Acellus app on your Kindle Fire is still showing a white screen and closing, so let's carefully troubleshoot this step-by-step with some focused actions specific to your device and app. Since you’re using a Kindle Fire with Android 9, here is what we can try:

1. Restart Your Kindle Fire
Hold down the power button for about 40 seconds until it shuts off. Then turn it back on. This often resolves temporary glitches causing white screens4.

2. Update the Acellus App
Make sure you have the latest Acellus version from the Amazon Appstore. Open the Appstore, go to "My Apps," and update Acellus if an update is available. Acellus recommends using their latest app on supported devices for proper functionality1.

3. Clear App Cache and Data
Go to Settings > Apps & Notifications > See all apps > select Acellus > Storage & Cache > tap Clear Cache, then Clear Data. This removes temporary corrupted data that might cause the app to crash.

4. Check for System Updates
On your Kindle Fire, go to Settings > Device Options > System Updates. Install any pending updates. System updates improve compatibility with apps and may include updates to Android System WebView, which Acellus relies on to display content correctly5.

5. Test Your Network Connection
A weak or unstable internet connection can cause the app to hang on a white screen. Try switching from Wi-Fi to mobile hotspot or a different Wi-Fi network to test if connectivity is the issue.

6. Reinstall the Acellus App
If you haven’t recently, uninstall and then reinstall Acellus. This refreshes the app files to clear out any corruption1.

If after these steps the app still goes to a white screen and closes, the problem may be more complex, possibly linked to your user profile or device-specific issues.
