I might have a similar problem. I was not using their desktop apps for some weeks, but I updated recently after they released a totally new app on mac os (different name so now I have two apps, ok) which I think is related to their name change. Since then, I can’t login in the new (or old) desktop app no matter what (the error was some connection issue I believe).
Haven’t reached out to support yet but it seems they are having some troubles in the transition?
