Hi there! I understand you're having trouble logging into the AlRajhi app on your iPhone running iOS 16.4.1, and you've already tried clearing the cache, reinstalling the app, and resetting but still getting an error. To help you better, could you please tell me the exact error message you are seeing when you try to log in? Also, are you connected to Wi-Fi or cellular data when this occurs?

Meanwhile, here's a step-by-step approach to try next:

1. Check for App Updates: Make sure you have the latest version of the AlRajhi app installed from the App Store. Older versions might cause login issues.

2. Enable Location Services: Sometimes the app requires location services enabled to function properly. Go to Settings > Privacy > Location Services, and check that it's on for the AlRajhi app.

3. Verify Network Connection: Try switching between Wi-Fi and cellular data to see if the issue persists. Also, try restarting your router or toggling Airplane mode on and off.

4. Reset Network Settings: Since you've reset the app and cache, resetting network settings can help fix connection errors. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Note this will remove saved Wi-Fi passwords, so have them handy.

5. Check Date & Time Settings: Make sure your iPhone has the correct date and time set automatically by going to Settings > General > Date & Time > set Automatically.

6. Try Logging in from Another Device or Web: See if you can log in to the AlRajhi web portal via Safari or another device to check if the issue is isolated to your iPhone app.

If after these steps you still get an error, could you share the exact text or a screenshot? That will help me guide you further or decide if we need to escalate to the technical team or check for service outages.

Are you okay to try these steps now?
