Google's depreciating "Normal password" authentication method and I am forced to switch to OAuth2. In Account settings I switch authentication method to OAuth2. Popup window appears asking me to fill my email, which is correctly filled, I click Next and I get the error message from the screenshot. Thing is if I start a fresh profile, I can add gmail account with OAuth2 just fine. I have cookies on and normal password removed from password manager for the account. Any idea if setting something in my profile can solve this?
