adobe subscription domain error 12

Purchased acrobat mobile around march and logged out of my apple id on my ipad to check some files on another icloud email but when i opened the app again, the premium subscription suddenly disappeared. i tried logging out and restarting my device and logging in again but i didn't do a thing, also tried restoring purchases but it said a subscription was found but i needed to log into that account. what irks me is that the icloud email i used for that premium subscription is what i already logged in to. please help, this is such a waste of money if i can't recover the purchase.
