Hide Parent folder for LMS Course Folders from Users
When you have courses folders created via an LMS integration, there is "parent folder" that houses all these course folders, and the admin can set the name of this folder in the iDP settings. In my case, it is called "Courses"
The problem is that all users see this parent folder in the browse menu when they are trying to locate a course folder. It seems that, by default, this folder is always collapsed. So users get very confused - they see a folder that is "greyed out," and does not have a red dot. If they clicked to expand the folder, they would see their course folders, not greyed out. But many don't notice the option to expand, or assume that because it is greyed out, they shouldn't click there.
I'm not sure what the best solution is, but I'm thinking that perhaps users should just not see that parent folder. Not having it greyed out would help

How I usually explain it to people is that "All Folders" is everything that you have access to in one way or another, where "My Folders" is the set of folders that you can manage/create content in. This list (IIRC) is expanded by default. This gets fairly confusing for folks, they often think that "My Folder" and "My Folders are two different views of the same content, which they very much are not.
I will also say that turning on the "Create Sub Accounts" IDP setting for Canvas helped us a lot here because then you can name that root folder something that would reflect the structure. I'm not sure what your LMS is, but if you have this sort of setting available, I would consider turning it on.
