Hello,
Thank you for visiting the Microsoft Community.
We noticed that you seem to be having issues with Microsoft Authenticator. I wish I could help, but it is more suitable to post in Microsoft Authenticator - Microsoft Q&A, more users post these problems there, you can click "Ask a question", there are experts who can provide you with more professional solutions in that place.
I sincerely hope that your query will be handled properly after contacting the appropriate department. Thank you for your understanding!
Best regards
Ian Ng - MSFT | Microsoft Community Support Specialist
