Could you please tell me which app MS acc refers to?
Is the account you are using a personal account or a work account?

2025-02-05T06:26:04.2833333+00:00 I found a method to fix this issue.
Precondition: use a work account
My method is that uninstall authenticator and teams app, then configure it again. -

2025-02-07T03:15:25.8466667+00:00 I have fixed this issue. So don't need your support for it now.
I used a work account. I use new android phone and migrate all data and apps from old phone.Resolution:
uninstall intune and authenticator apps, then install them and reconfigure them.
