The OP is re-tooting a toot of a screenshot of a tweet. My (mild) criticism isn’t aimed at OP, nor the OP of the OP, just the original Twitter OP. No one was “blasted” but even if they were, the Twitter OP is not likely to see my comments and have a bad case of the sads from it.
I can’t speak for all Jellyfin clients since I only use Android TV and Windows clients but on those two platforms you can tell Jellyfin to continuously play or to stop/prompt at the end of each episode.
