Hello Microsoft Support Team,

I am experiencing a recurring issue with Microsoft Authenticator on my Samsung Galaxy S23 Ultra.

App version: 6.2610.7075.

The application frequently freezes on the startup logo and displays the error "Authenticator isn't responding."

Sometimes the app opens normally and displays all my accounts and verification codes, but the problem returns the following day.

I have already tried:

  • Updating Microsoft Authenticator.
  • Force stopping the app and clearing its cache.
  • Restarting my phone.
  • Checking battery settings and automatic date/time.
  • Switching between Wi-Fi and mobile data.
  • Updating and reinstalling Android System WebView updates.

Unfortunately, the problem persists.

Please investigate this issue and provide a permanent solution compatible with the Samsung Galaxy S23 Ultra.

I especially need instructions to fix the problem without losing my saved authentication accounts, verification codes, or sign-in approval functionality.

Thank you for your assistance.
