The apps don't work well at all. If you're just desktop based, its fine. But Nvidia Shield app, firestick app, mobile app, all have issues with hardware transcoding, and also somehow doesn't handle subtitles properly. I have had both Plex and Jfin set up side by side multiple times, trying to test if I can make the swap. But JF just has too many bugs on their apps, which is what I use primarily, as do my users.
