I had a non email apple ID from years ago. I recently purchased an iphone and tried to use iCloud. It prompted me to verify email address by inputting code sent to email. after entering code i get error stating email unavailable. Now I can not access purchases from old non email ID. I enter non email ID in appleid.apple.com and it says does not exist. I see no way around this. I also signed up for apple music and not sure how I can cancel. any help is greatly appreciated.
