On the new interface when we create a new empty repository :
all users with Write or Admin permissions don't have the "Watch" button on the overview page nor the repository URL (but the latter can still be found when clicking on the Clone section)
users with "Read Only" permission have the "Watch" button and the repository URL directly on the Overview page.
It's not critical but it's annoying as we cannot directly add the repository on SourceTree from the bookmarks as long as it's not watched.
Here is an attachment of the Overview page with users having Write permissions. The top right corner lacks the usual component letting people watch the repository and the repository URL
