iOS 16.1.1 won’t let me sign in to a different Apple ID for iMessage and FaceTime
When I go into iMessage settings -> send & receive -> tap the link with my Apple ID -> select sign out.
Then I tap Use your Apple ID for iMessage -> Use Other Apple ID, and after 5 seconds it just signs me into the same Apple ID the phone is using.
How can I fix this? I tried signing out of both iMessage and FaceTime, turning off the phone and waiting 30 seconds but it’s still not working.
The phone is brand new, no apps installed yet.
