.... yes I'm using the latest kodi alpha nightly build of Leia... ok you are not interested, no issue. Can you please tell me where in the code you are loading the settings for the 1_vpn_addons setting? Where is the verification line?
By no means the right way or a solution but if you are after a similar temporary work-around then a bodge to the filtering by amending the server.py just to force a disconnect on Netflix or whatever you need (around line 600, add the 'OR 'and restart the Pi):
if filter == 0 or ("flix" in current_path):
Better than nothing for the moment
