I have two problems. First, I have admin rights in OG Professional and created a new project in Professional. I can see the project in Collector but when I "Select Project" I get an error message "There are currently no downloaded data entry profiles" (see photo below). So I can't do anything more and I can't enter data. This problem appears to be specific to me because another user, who also has admin rights, does not get the same error and can enter data into the project. I am using OG Collector on a Samsung Galaxy Tab S5e and I am the only user logged into the tablet.
The second problem is that when I sign out of Collector and my coworker signs in Collector still shows my profile. The person trying to sign in has a CONNECTION Client account. I've given them access to one project but they can see all projects in the Collection app, as if they had admin rights. The photo below shows my initial "J" at the top after they've logged in.
