Playback trouble? Another Roku option
JellyRock is another maintained Roku client, led by a former official-client maintainer. It can be worth trying for audio, subtitle, or playback problems. That history is useful, but does not guarantee every file will play better.JellyRock installation →
Use the same full HTTPS server address and Jellyfin account. Ask Cruv if you need help choosing a Roku app.
Why this app? Details and sources
The official Roku app remains actively maintained and has a longer household-use history. Reports about alternate Roku clients are mixed; there is not enough evidence to replace it universally with Moonfin. JellyRock’s maintainer history makes it a worthwhile playback alternative.
