My iPhone 14 Pro won't let me disable "Find My Phone" to wipe it off
I have six fully paid-for iPhone 14 Pro phones. I changed carriers - from AT&T to T-Mobile. I'm trying to wipe all the phones to sell. They are unlocked. However, I can't turn Find My Phone off, so I can erase/reset them. I've tried entering the password several times, and it seems to work, but after about 30 seconds, it reverts to the sign-out screen. Any suggestions?
