Yes, sorry, didn't have time to research this. Not sure what could the cause be. If you cannot log into Google from Odyssey (without going through the Iris configuration), then it likely means that some of your settings (not 2FA itself) is preventing the login. I can only guess which one since people seem to be getting this error due to many different issues it seems.

I don't think I've tried using any Google login workarounds, so maybe try with that disabled.

I'm looking into getting Iris certified in the next couple of weeks, so perhaps that helps. It seems you're the only 1 person actually being blocked from signing in to Google. Certainly odd.
