I’m not sure why you posted an image of it working on a 4K instead of showing what your seeing on a V. As you can see from what I posted it should be there. Perhaps you can try resetting the OSMC skin and see if that changes the behavior.
I believe so. Because these two mounts belong to user root and group root, and since you are neither, then the other permissions are the ones that are in effect and those are currently set to execute only so your lacking read permission.
