Apple ID and iCloud Authentication Issue
Greetings everyone,
I am encountering an error related to the authentication of my Apple ID and iCloud.
Although I am entering the correct credentials in my browser, I am able to log in at https://appleid.apple.com/ but unable to log in at https://www.icloud.com/.
An error message appears near the password field stating "phone number cannot be blank." I am unsure how to resolve this issue.
When attempting to reset my password, a verification code is sent to my trusted phone number. However, after entering the code, I receive an error message stating "verification issue, an unknown error has occurred."
I would greatly appreciate any assistance in resolving this issue.
I am also unable to turn off the "find my phone" option, which prevents me from resetting my iPhone in order to use a new Apple ID.
Thank you all for your help.
