The 0.18 version of the AndroidTV client fixes the subtitle loading issue, and it offers trickplay (scrubbing with images) as an experimental feature you can turn on, assuming you’ve generated the trickplay images server-side.
If you add yourself to the Play Store beta for the app it should update to 0.18 right away, otherwise the rollout for it is in progress.
Any other issues? I hang out with the Jellyfin devs in their chatrooms, could relay issues to them.
