Hi @tommaso-moro @giddyphysicist @Julitocast
Sorry to hear you’ve experienced that issue, and thanks for reporting it 
The issue seemed to be caused by a bug invalidating the anonymous users’ sessions whenever someone disconnected Github from their account.
That bug was fixed today and released, so users should not encounter the issue anymore, yet please let us know if you’re still experiencing it.
Happy Streamlit-ing! 
Charly
