We are having an issue when users attempt to log out of Revit 2020. We are working on two separate hubs and we are only having this issue when logging out of 1 hub, the other hub functions properly. When we attempt to log out all we get is an hour glass symbol. We attempt to log out several times without success. If you end the revit 2020 process in task manager, Revit will not open again.
Our work around it to open another version of revit (ex.: 2019) and logout and then launch Revit 2020 and log into the other hub. I suspect Revit is getting confused between the two different Autodesk accounts and log in/out functionality.
