Couldn't sign in to iMessage
I could not sign in to my iMessage on MacBook Air with my Apple ID.
It shows "An error occurred during authentication."
I created my apple ID in 2017 and currently using it.
I have tried all the tips from https://support.apple.com/en-us/HT204408 this page.
However, I tried it with my sister's account and it could sign in.
So, I would like to know if my Apple ID is having issues with iMessage.
MacBook Air 13″, macOS 10.15
