Hi there! I see you're encountering a black screen when opening the Glint app on your Android 10 device. Let's get this sorted out together.

To start, could you tell me:
- Did this issue begin after a recent update to the app or your device?
- Have you tried restarting your phone or reinstalling the app yet?
- Do you have a stable internet connection when opening the app?

Once I know this, I can guide you more precisely. Meanwhile, here’s a simple process we can try:

1. Restart your device: Hold the power button and select Restart. This often resolves minor glitches.

2. Clear the app cache:
- Go to Settings > Apps > Glint
- Tap Storage > Clear Cache
This removes temporary files that might be causing display issues without deleting your data.

3. Force stop and reopen the app:
- Settings > Apps > Glint > Force Stop
- Then open the app again.

4. Check for app updates:
Go to the Google Play Store, search Glint, and see if an update is available. Using the latest version ensures compatibility.

5. Reinstall the app:
If none of the above worked, uninstall Glint, restart your phone, then download and install the latest version.

Since you are on Android 10 with WebKit, some app display problems can stem from outdated app versions or cached data conflicts.

If after these steps the black screen persists, please let me know. We can then verify account status or check for known server issues.

Are you able to try these steps right now?
