At "Sign in with your Apple ID" screen I get error message "Account_Unavailable."
New Macbook Air M3. At "Sign in with your Apple ID" screen I get error message "Account_Unavailable." I have no sign in issues when accessing https://account.apple.com/sign-in or https://www.icloud.com/ . In the account settings I have successfully verified my email address (Apple ID) and updated some setting information. I even reset my password successfully. I successfully removed this email address as a secondary (not primary) address on my company Apple ID account. I have no clue why it's not working and I really don't want to setup a new email address and new Apple ID.
