Hi @Greg_Purkis
Apologies for the delay. I do understand the confusion around the Collaborator/Admin role when the user joins the workspace. We are working on making this more intuitive but, this is the expected behavior in the latest version of the app. Please refer to the below useful article to know more about different roles & permissions available in Postman:
[https://learning.getpostman.com/docs/postman_pro/managing_postman_pro/roles_and_permissions/]
With regards to the admin having access to change the roles, unfortunately, that isn’t how it is designed. The Admin role has rights to make changes to the workspaces and not to the roles of collections within them. This right is yet reserved only to the owner of the collection. I would suggest you check with the above article, which should clarify your concerns with the permissions.
