I shall just wait for the updates, I think I’m well boned at this point 
Edit: The NAS issue seems to have just been related to the Plex server permissions, separate from the USB issue. So that’s sorted for me (see: Nvidia Shield update removes Plex Server Permission). Unfortunately…my Plex database was wiped due to the files being inaccessible, but at least it works with my NAS storage again.
