I have the same problem could you solve it? This happens to me when I give read-only access to folders and the problem is only reflected in browsers since the mobile application is working fine.
the only solution that I could find is to give an empty folder with all the privileges with all the privileges, and the other folders that I want to share just give them read access, apparently when trying to access via the web, it has conflicts with the permissions of folders, but that solution helped me, try and tell me.
I used your recommendation and it resolved my issue. Is there a software upgrade or another permanant fixed for this issue? Reason for asking is too many folder are being created and it is cluttering my dash board with unnecessary folder which are not bing used for the intended purpose of the system.
