I am using Pega cloud trial. It works fine in the beginning. I follow video to create new role - Developer with "Case Default" as the channel Interface. I then create people with Developer role and invite to my application. Co-worker is able to join the application. However all he can see is the "Case Worker" view. His UI didn't allow the "Turn editing on/off". What we should do to let "Developer" role participate to work in Case type?
