This is a problem I have had since the beginning. With sync, I would sync my albums once and it was done. Now I try to use the downloads function, and it downloads everything. Great. Then the next day, I see that it is redownloading everything. This is especially frustrating given that I use plex when I travel on planes and do not have access to streaming. If this function isn’t working, I may need to look into a different option. I have been raving about plex for years to friends, but right now I am not recommending the setup with this feature being broken and no one responding to anyone on these threads.
