Unlock request for out of contract iPhone7 doesn't work
I have just upgraded from couple of iPhone7 to iPhone XS in late November. I made sure all the iPhone7 is not under any contact before upgrade. AT&T accounts shows that iPhone7(s) are not in my account. However, while trying to request for unlock at AT&T unlock portal, for one of the phones displays a message "Looks like you haven't paid off your device yet. Follow these steps to pay off your installment plan. Then, wait 48 hours before you submit a new request". The other phone unlock request goes through and I get the unlock approval and instruction.
Interesting part is that I had paid off both iPhone7 at the same time days before Thanksgiving day.
Looks like portal database is not synced up with the AT&T system.
Need AT&T assistance to resolve this issue. Appreciate any help.
