I recently turned on Advanced Protection for my Google account. I was able to log in on my desktop with no issues using account name, password, and security key. However, I have been unable to log into any google apps on my iPhone (iOS 13.3) since enabling AP. I get an error messages saying "Google couldn't verify this account belongs to you. Try again later or go to ... for help."
After I noticed this problem, I turned off AP for my Google account, but am still unable to log into mobile devices. I get the same error message, even with AP turned off for my account. I have tried changing account password, but that does not solve the problem.
I have tried reaching out to Google for over a week with zero response (Christmas and NYE is a tough time of year, I know).
Does anyone have experience with this and know what to do to fix it?
