I'm trying to add a user to have permissions for a repo I have recently setup. I've been able to add this same user to repos previously, it's not something that I do frequently though and looking at the online documentation it show's a '+' button should be visible (see below)
However there is no '+' button visible to me (either initially or after I search and select the person I want to add), see below:
I do not believe any permissions have changed for my login since I last did this for another repo, so I wouldn't expect the '+' button to be hidden from me.
