Can’t log in from GMail iOS app with email

[semistrict]

When the login link opens, GMail opens it in its internal browser and then redirects to the system browser which then says that the login link has been used before (presumably with the first request from the internal browser). I believe all iOS GMail app users would be affected. Also cannot log in with Discord now because my email is already recognized by the system so I currently have no way to log in at all.
