auto smush not working with BuddyPress / rtmedia / multisite

hi,
basically i am trying to use the new "Enable Network wide settings" in SmushPro and i have
"Automatically smush my images on upload" selected.
but on main site (multisite) the uploaded images do not smush automatically if used on the front end via rtmedia.
they do automatically smush and work fine if using the default wp media upload via admin.
i tried deactivating, deleting and reinstalling plugin but same problem.
support access granted if needed,
screenshot attached of settings for your perusal,
your kind assistance and support here would be greatly appreciated.
kind regards.
