I use a Google account for my association that several of us use. For several years, everything had been working fine. But recently, other users can't click on their phone number to review their code by SMS.
On the Two-Step Validation page, where it presents the options you can choose to perform verification, all the SMS verification phone numbers are there but they are now grayed out and can't be clicked on, and each has a note below the phone number "Unavailable because you have more secure options"
All the phone numbers have been verified.
Do you know a solution? In the capture, I can identify myself with the YouTube application but it works for me because I am the account manager. It doesn't work for the other people. I know that Google doesn't intend for people to share an account and not sure if that is the problem.
