Hi again @mick-mcbride - So I was incorrect about that. It seems that this is actually not a bug. Apparently team admins can only manage team-wide roles, i.e. assign other admins, billing users, and developers, but they don’t have access to every single collection. The owner of the collection or any team member who has editor access on the collection will have to assign you the editor role for the collection to allow you to manage it. Sorry for the initial mistake!
