can't login to apple id
My 2nd time asking, I had an apple Id since I got my first ipad air, and I had to reset it cause it was full, it logged out my apple id, now to log in, I need a phone number, which doesn't work anymore, I remember the email and password, I have ipad air and I cannot use account recovery because I need IPadOS 15 or macOS Monterey, I have neither of those, ipad air last update is iOS 12.5.5, I spent money on this account, is there a way to get my account back with a different phone number?
