All of my projects seem to be working right now but when my project wasn't opening, none of my projects opened.
I regret to say that I didn't even think of using a different browser. That's like troubleshooting step 1 so I feel stupid.
Screenshot not available, as I all my projects are working right now.
I don't really have a problem right now, as my project just opened. But I suppose if there are more issues in the future this would be some more documentation.
-----EDIT. It just happened again and I think I know why. I was doing a computation and it was taking a long time and the 'Interrupt R' command didn't seem like it was doing anything (for like 2 minutes), so I just closed the tab, and when I went back into r-cloud it gets hung up on 'Opening Project'.
