Hi! It sounds like your America First Credit Union app screen goes black when you try to log in on your Android 10 device with WebKit browsing. Let me help you get this sorted out.

To start, can you tell me if this started happening recently after an update, or has it been like this from the beginning? Also, have you tried closing the app completely and reopening it, or restarting your phone? That helps clarify what we've already tried.

Meanwhile, here are some step-by-step fixes you can try:

1. Force close the app and reopen
- Go to your device Settings > Apps & notifications > See all apps
- Find and tap America First Credit Union app
- Tap Force stop, then open the app again.

2. Clear app cache
- In the same app settings screen, tap Storage & cache
- Tap Clear cache (this clears temporary files that may cause glitches, no personal data lost)
- Open the app again and try logging in.

3. Check for app updates
- Open Google Play Store, search for America First Credit Union.
- See if there's an update available; if so, install it and try logging in again.

4. Check Internet connection and VPN settings
- Make sure you are connected to a stable Wi-Fi or mobile data network.
- Disable any VPN or private network apps you might be using, as these can sometimes interfere with login.

5. Reinstall the app
- Uninstall the America First app fully.
- Restart your phone.
- Reinstall the app from the Play Store and try again.

If after these steps the screen still goes black on login, it could be related to an app compatibility issue or server-side issue. Sometimes specific device/OS combinations may have bugs that need patching. In that case, contacting America First Credit Union support directly or sending an email to [email protected] can help escalate the problem.

Also, one user reported that disabling iCloud Private Relay fixed login issues on iOS, though this does not apply directly to Android, it shows login screen blackouts can relate to network privacy features1.

Please try the above and let me know if the issue persists or you run into any trouble during the steps. Are you satisfied with this guidance so far?
