I'm actually facing the same situation because of a 'use-case limbo' and I'm devastated. Google is locking me out of my 11 years old Google account (Gmail, Adsense, YouTube, Analytics, ...) I use for a side project (electronic music blog) because I'm trying to log in from a new device/country/IP. Alright then, I'll try to recover the account with the security question or the recovery email. Nope, Google doesn't even let me enter the recovery process because of the same error. I can't do anything because of a stupid flag on the account. The best part? Everytime I'm trying to log into my account, I get a security alert email sent to my recovery email. I can say to Google that I don't recognize the connexion (AccountDisavow) but I have NO OPTION to allow it. What's the point of having a recovery email? Can't Google see that it's the same IP trying to log in and trying to access the "Review activity" from the security alert email? If any Google employee is reading this, I'd love some help!
