Unable to login to ATT Email- "We've detected a SIM Card change"
I recently upgraded my Iphone 11 Pro to a 15 Pro, and i've been unable to login to my ATT Email on ANY device. For the MF Authentication, I keep getting the error "We've detected a SIM Card change. Select try another way to use a different mobile number" when entering the security code.
Then it just prompts you to send another code to the same number- and the issue repeats. Is anyone else having this problem or is there a solution yet?
