Google Services/Logins No longer work with Brave

[Mattches]

This is a known issue that we’re still working out. However, users have been able to resolve it by lowering shields on the login page and the 400 error page:

Cannot log in to gmail (Error 400) after updating Brave

thanks wizzin, that solved the issue for me! what I did was to set brave shields to “down” on the gmail login screen, they stayed down through the rest of the logon process (pw and 2-factor authentication) and then gmail loaded. I have tried other proposed solutions (clear browser data, cookies only on 3rd party, open it in private window) which had made no difference.
