Hi there! I understand you're having trouble logging into the Monument Bank app on your iPhone with iOS 18.7. To help you better, could you let me know if you are seeing any specific error messages when you try to log in? Also, have you recently changed your password or updated the app?

Meanwhile, here are some initial steps you can try to resolve login issues:

1. Make sure you are using the latest version of the Monument Bank app. Sometimes an update fixes bugs.
2. Try closing the app completely and reopening it.
3. Restart your iPhone to refresh the system.
4. Check your internet connection to ensure it is stable.
5. If you see an error like TS:8, try uninstalling and reinstalling the Monument Bank app, as this can fix app-related glitches.

If these steps don't work, please share any error codes or messages you see, and we can dig deeper into the issue.

Are you currently able to access other apps or websites without problems? This helps confirm if the issue is isolated to the Monument app.

Unable to logon

Thanks for confirming you're unable to log in. A common and effective solution is to uninstall the Monument Bank app from your iPhone and then reinstall it. This often resolves issues that happen due to app glitches or corrupted files. After reinstalling, when you tap "Log in," if you're unable to remember your PIN or password, use the "Forgotten pin" option to reset it by following the on-screen instructions.

Here’s a quick step-by-step for your iPhone (iOS 18.7):

1. Press and hold the Monument Bank app icon until it shakes.
2. Tap the "X" to uninstall the app.
3. Open the App Store, search for "Monument Bank," and reinstall the app.
4. Open the app, tap "Log in."
5. If you don't recall your PIN or password, tap "Forgotten pin" and follow the reset steps.

If you still face trouble logging in afterward, please share any error messages or behaviors you see. That way, I can help further or check if there are any ongoing service issues.
