According to your description, I'm sorry to hear you're having trouble with the Microsoft Authenticator app on your iPhone 15 Pro.
For this unexpected behavor on your iPhone15, would you please try following steps and see if it can make any differences:
- Restart Your iPhone:
- Sometimes, a simple restart can resolve many issues. Press and hold the side button and either volume button until the power off slider appears. Drag the slider, wait for your iPhone to turn off, and then turn it back on.
- Check for iOS Updates:
- Ensure your iPhone is running the latest version of iOS. Go to Settings > General > Software Update to check for updates.
Then have a check and see if the Microsoft authenticator works or not.
