Hi there, it's way too difficult to manage permissions for a project. I wish it were more like Google Docs, where as the manager of a project, I can add/remove user access as needed for a particular project. We do internal research where it could be incredibly damaging for viewers to view their colleagues' raw data without consent.
Because of nested permissions, where the folder permissions supersede individual project permissions, I can't remove an individual user who absolutely shouldn't have access to a project. (Google Drive also has this problem when certain permissions are applied at the folder level - another huge pain for people who do work like we do. So much time wasted copying, deleting, and re-uploading things, oftentimes having to bring in IT who are the only people with full admin permissions.) To solve my current issue, I'm going to try to delete the project entirely, which hopefully I have permissions to do.
