fyayc-bue I agree, i also experience this issue from time to time and since multiple years. I could notice that I can provoke it by clicking on a Teams group instead of opening a chat or a meeting. However, I found a workaround when it happens: close the Teams app and the authenticator application. Then you open only the authenticator and wait until Face ID has authenticated you and you can see your accounts. Then you open the Teams application and it should work again. I believe the problem is related to using Face Id to open Authenticator in combination with enforced MFA and/or risk policies.

Can you test unlocking it without using face id? cause this seems like a bug with face id and authenticator, some disconnect. Needs to be reported to devs.

    Dear PlanetDDS_JeremyZ
    I don't use FaceID. My phone is actually too old to support it :unamused:
    But as it came, the infinite loop went' away two days later.

    Without any change on my side.
