I cannot log in to my work account using SMS authentication

Thank you for your reply.

I have already tried the following during login.

The Phone call option does not work, I get the same error.

Unfortunately, I do not have the authenticator anymore, as the setup was lost due to a phone change.

I am able to receive SMS messages from other sources on my phone without any issues.

And unfortunately, this is the one and only admin account.
