Old apple id, email doesn't exist
HI, i just updated an old iPhone 6 to an iPhone X, and i cant do anything because it keeps asking me to log in to an old apple id which doesn't exist. I did switch it, but some old purchases seem to be there. The challenge is that when i google it it is asking to change the email back to the old one, and then change again to the current. But the OLD email doesn't exist anymore, it was an old work account...
Is there not an easier and quicker way to fix this?
