Hangs on 'Loading...'

My attempts to open rstudio cloud just hang on 'loading...' in the top left corner of the screen
Unfortunately, I just had a quick look at cloud a while ago and then was planning to come back now, so don't have the project id to hand
Is there any way this can be fixed/looked into?

Not without knowing the project id.

OK but even when I try and access via just rstudio.cloud it hangs. Having read other threads on this problem I expect this is because I quit the cloud before closing the project. Is there no way to "start over" as it were?
I am a huge advocate of rstudio and the cloud would be so useful to me
