Jellyfin's support for Audiobooks is still fairly rudimentary. Most of the features mentioned depend on the client app's level of support. There's a feature request that details some of the support already in place: https://features.jellyfin.org/posts/243/audiobook-support https://features.jellyfin.org/posts/243/audiobook-support Support for resuming Audiobooks appears to have been added: https://github.com/jellyfin/jellyfin/issues/2084 https://github.com/jellyfin/jellyfin/issues/2084 Sadly offline playback isn't really supported. The app can download files to your phone's Downloads folder but you'd have to play them elsewhere. There's no way of so through Jellyfin at the moment.
