Figured it out.....
First problem was naming the files....dont have to put .mp4 and .funscript in the name, that is just part of the file extension so just name them the same.
Second problem was plex. It adds the year to the name of the video so pay attention to what it comes up as when you play it....then add that to the file name of the funscript.....
Just put the funscript files into the interactive folder in the root of the oculus go.
Feel like I wasted money on the subscription tho
