Hi, I'm wondering if anyone having issue today after the Microsoft Authenticator update (Version 6.2405.3618) on Android? My Outlook app suddenly asks me to sign in again with our Office 365 work email, and if I tap on sign-in, it will show "Updates required - One or more of your apps are out of date. Please update your apps to continue" error message (I also have sign-in issues with Word, Excel, Microsoft 365 Admin apps, but for some reason OneDrive and Intune are not affected). After multiple re-tries, I ended up clearing Outlook app caches and data. After that, I'm unable to sign in to my Office 365 work emails as either it is stuck on the spanning circle or the same "Update required" error message, but my personal free Outlook email with MFA can sign in without issue. I've manually checked the Outlook app and Authenticator app on Play Store and both show no updates. I also clear Authenticator app data and recover everything from the backup, but still the same issue. (I'm on RedMagic 8s Pro with Android 14)

    I confirm that uninstalling MS authenticator mitigates the very same issue with Teams. It is a shame that Microsoft has not taken any actions after that much time to solve the problem at once.
