Hi,
I used to connect authenticator app on Android with MS365 business account for 2FA login. I also managed to add many private accounts for 2FA, also my private M365 2FA login.
After changing the job they deactivated my M365 business account. So long, so good. But I'm not able to delete the deactivated M365 business account out of the MS Authenticator app. It's greyed out and I can't open the settings to delete the entry out of the app.
Is there a way to do so and if not, what steps can I do to support you in investigating this issue further more?
