I will post an error, but I can not log in.
When I open the address https://bugreport.apple.com, I am requesting log in. Ok, I tried my three different AppleIDs, and all of them give me the same error message:
The account does not exist. . This is very awesome.
I can use the three AppleIDs to log in to icloud.com without any problems. So what can I do to log in bugreport?
