Bug Update: The Schools Login Bug
I'm happy to say that our hard working developers have fixed the login bug that have become a recent concern in Duolingo for Schools.
All teachers should now be able to login using the portal on https://schools.duolingo.com/ without issue. If you encounter any issues logging in on this portal following this message, contact us here or in support.
Thanks for your time and patience shown while this was being investigated and resolved!
