Hi!
So I put in my username, my password, I watch the bright red login button go spinny for a couple moments, and then I get this screen, where it tells me I am Schrodinger's Logged In. Logged in, but also not logged in.
It seems to work in Chrome, but I very much prefer using Firefox for privacy reasons. :)
Remove cookies and repeat
this fixed it for me. you can do that by clicking on the lock in the URL bar and then clicking on "clear cookies and site data"
That fixed it! Thank you!!
