If my Apple ID says that it’s invalid or unsupported what does that mean(I just reset my phone and did a new Apple ID on the phone. I did not delete it)but now I want my old Apple ID but it says it’s invalid or unsupported
I had a phone and I did an Apple ID for it(it was new iPhone 14) but after a while I wanted a new Apple ID so I reset my phone and did a new Apple ID (I did not delete it) and now I want the old one back but whenever I try to change the password (cuz I forgot it ) it says it’s invalid or unsupported. What should I do?
