Apple-ID is doesn't exist so now I can't log out from it!
I'm reposting this question to garner more attention and no I can't go to my school. Now onto the question at hand. I graduated from my school and got to keep the iPad which we got when we started. It had a school Apple-ID account and once we graduated they deleted the Apple-ID:s. So when I try to log out of the non existent Apple-ID it gives me an error. "verification failed, cannot find this person". I have 2 Apple-ID:s logged onto the iPad but it still asks me for the password for the one that doesn't exist. Is there some, I don't care if it's a third party or not, solution to this problem? Since Apple obviously didn't think to have a good solution to this problem.
I cannot update certain apps because of this.
iPad Air 2, iPadOS 13
