Please click on this link and read "What to do after [or before] you change your Apple ID [email address] or password" ➔ https://support.apple.com/HT204071 - "After you change your Apple ID email address or password, you might need to update your sign-in information with any Apple services you're using." - Or if you're seeing persistent disabled messages or repeated requests for the password to your previous Apple ID. You may also wish to turn off "Find My" before changing information and turn it on again afterward.
"Verification fails" is something else. "If you can't connect to the App Store, iTunes Store, or other Apple services" click here --> https://support.apple.com/HT201400
- If none of the suggestions work, try the last one: "If you’ve tried all of the above steps and you still can’t connect, contact Apple Support."
If you can't connect or sign in to iCloud --> https://support.apple.com/HT203512
