1Password complains Opera GX Browser is not up to date

Thanks for the info @vamfoom .

We do not have special plans for Opera GX.
I did, however, tried replicating the issue and everything seemed to work correctly for me. The error you are describing sounds like something that our web app might show (when you try to log into your account on our website), but not the extension itself. Is there a particular reason why you are trying to log in via our website and not directly via the extension on the top right corner of your browser?
