Multi-Factor Authentication Issue
I am having an issue since I replaced my old Pixel 2 XL on my account with a new OnePlus 8 Pro yesterday. I have 3 lines on my account, but now my number no longer shows up on the screen to validate. I spent a significant amount of time on the phone with support at the 800-331-0500 number, but they very clearly did not understand the issue and kept talking about password resets. They also did not have any way to see a screenshot of the issue.
I just want my number to show up on the below screen (and in the myAT&T app) so I dont have to pester other family members to get a code. Also, I am the primary account owner, so I can just imagine the issues that single line owners would run into.
Does anyone have any keywords or departments that understand this and can resolve it?
I really would like for all three numbers to show up so I can access to my account.
I wont even get started on the frequency of these MFA prompts, because I know it is there to prevent fraud and the tech industry still does not have a more user friendly and less invasive option available. :(
