Hello,
I'm having quite similar issue to which is reported here.
After creating a new workspace (why was the old and simple way of creating it got changed?!), the workspace got created with the following header up above WITHOUT ANY OPTION TO CREATE A NEW PROJET NOR REPOSITORY under it:
"Workspace setup in progress. Groups and users may not be fully available for multiple hours. This banner will disappear once the process completes, upon page refresh"
It has been already about 3-4 days since the workspace was created and nothing is changed since then.
Cheers,
Ran
