I have a shit spyware android box with Emby installed, use Emby server (lifetime sub) i use it on my phone too. Have been usingn Emby for about 5 years with 0 issues. Have even brought my server across 3 or 4 installs
My Emby server is also my main PC so to preserve my SSD’s i use a ram disk to store the transcoding data
Emby has lots of plugins for statistics so I dont bother with Trackt but does have a telrackt tv pkugin for auto syncing
Jellyfinn is the same base software as Emby but ive never used it
KDE Connect should do the trick
