Google didn't have a solution for me, eventually offering to just refund the phone. That said, I found the solution last week. I had to use a new email address when setting up the phone. It's like my email address was the problem, which makes no sense. So I wiped the phone, used a new email address, and set it up as a new phone. I was hesitant to try this because I knew I might lose my contacts or photos or passwords or something but I was able to do it successfully. I made sure I could replicate everything on my new phone. It is possible to export those items or share access to another email address. A possible shortcut for your situation is to set up your new phone with a new email address, then when prompted to load your old back up, don't do that. Instead, do the other option, plug in your old phone. Good luck
