I got a new phone, my old one was a Huawei made 10 Lite and the new one was a Huawei made 10 Pro. Then we made this phone-clone and then it was all on my new phone, but when I went to YouTube there was an error and I was logged out then I could only log on to a new email address and when I got it I tried with my old stand there this email address already exists, but I can't log on and I'm really desperate because this is very important, please an answer. Many Thanks

I have now deleted my new email address and wanted to log in to Chrome then I enter my old email address and the password and suddenly it is the new again although I have entered the old one.

You probably want to register again and do not sign up…

So if I zbs on Youtube. Go to accounts is my new with the new email address, and then on + then it says: Sign in with your Google account then I enter the old address and then there's this account already exists but that is it not.
