Hey! Yeah, I am having the same issue, have tried logging out, hard refresh, etc, but cannot open existing projects or create new 🙁
Ye I was hoping to get it exported into Figma this morning. I hope it is sorted soon.
to follow up on this - it appears that there was a regional Amazon/AWS outage that caused this issue. It resolved itself because the services came back online. Apologies for the issues there.
