Hi there! I'm sorry to hear that your partner's new phone is causing issues with the app. It can be frustrating when things don’t work smoothly after a device change. Let’s get to the bottom of this together!

Can you tell me a bit more about the specific problems you’re experiencing with the app? For example, is it not opening at all, crashing, or giving an error message? Also, would you mind sharing what phone model your partner has and whether the app was working on their old phone? This additional info will help me guide you better!

App is showing a blank screen

Thanks for that detail! A blank screen can be quite annoying. Let’s try to troubleshoot this step by step. Here are some possible solutions we can try:

1. Force Close the App:
- Swipe up from the bottom of the screen (or double tap the Home button if your partner's phone has one) to see the app switcher.
- Swipe the Kstert app up to close it completely.
- Reopen the app to see if it resolves the issue.

2. Check for App Updates:
- Open the App Store on the new phone.
- Tap on your profile picture in the top right corner.
- Scroll down to see if Kstert has an available update. If so, update the app and see if that fixes the issue.

3. Restart the Phone:
- Sometimes a simple restart can do wonders. Ask your partner to turn off the phone and then turn it back on.

4. Check for iOS Updates:
- Make sure the device is running the latest version of iOS. Go to Settings > General > Software Update and check for any available updates.

5. Reinstall the App:
- If the above steps don’t work, uninstall the Kstert app and then reinstall it from the App Store.

Let me know if any of these steps help, or if the blank screen issue is still there! We can continue from there.
