Whatever the account, groups or rôles, i'm not able to save dashboards in "shared folders".
I do not see shared subfolders under "shared folder" in the directory tree (even with Administrator & Enterprise Designer Role) :
The message in French to US : "You do not have access to this folder for recording."
Only "Administrator" account can do this.
With Dashboard Designer, starting with Tools/Folders, I can't "modify directory" on "shared folders"
What's the matter ?
