Microsoft Authenticator

Question

Hi, yesterday I turned power bi mail account into ADMIN (https://admin.microsoft.com/admintakeover#/admintakeover)
Right after that when I tried to login I get this message:

The translation is the following:
I should open Microsoft Authentication and aprove a request in order to be able to login

The problem is that I get the same message in the mobile when I tried to add that power bi mail account .
I get into a loop that I do not know how to solve

Any ideas ?

Thanks
