An integrated threat protection solution designed to detect, investigate, and respond to cyber threats across Microsoft 365 services.
Emmanuel,
Thanks for your reply. I tried reinstalling using the method you suggested and it did not help, I still get the same error. My child's email address was just created and is purely associated with the Microsoft Family account. It is being spelled correctly. Again, I am not getting an error related to invalid username or password, but that the "license" associated with the accounts are invalid.
As I mentioned, these Microsoft accounts were just created for this purpose and are not associated with any work or school account. This same issue is happening with two separate accounts on two separate Android devices. Any further assistance you can offer would be appreciated. Thanks.
