I can't log in to Teams account because my authenticator app isn't working

I haven't been able to get on MS Teams work accounts for months because the authenticator app isn't working. The App is there and open but no number pops up on it when it should.

I've tried calling microsoft support, they tell me to fill in an online form - which I need to log in for!!

Everything I try and do I need to log in, when the problem is, I can't log in.

My business is just me, so I assume I am the admin, but have been added to client accounts which I now cannot access.

It's so frsutrating, I wish I had never bothered with Authenticator, and MS Support is non-existant.

    Hi @Sharon Slinger

    If you're using mobile data, try switching to Wi-Fi and vice-versa. Make sure Airplane mode is off.

    Make sure you're using the latest version of Authenticator - Microsoft does not support any app versions more than 12 months old. Tap Settings and make sure App updates is turned on. Get the latest.

    Tap Settings and select Turn off battery optimization for better sync performance.

    Tap Settings > Notification Settings and make sure Show notifications is turned on.

    Make sure your device is up to date, and that any other security apps (such as Microsoft Defender and Intune Company Portal) are also up to date. Make sure the device's  Date & time are correct too.

    If you're using VPN, try disconnecting to see if the issue persists.
