Yeah it's pretty powerful, the `sync` mechanism is pretty good at handling offsets and timing. Sometimes (rarely) it requires manual intervention, but it's still very good. Best thing out there for automatic sub scavenging and sync, and being able to run it Dockerized helps a lot. Radarr, Sonarr, Lidarr, Bazarr and Readarr are all mostly the "same ecosystem", and LSIO has them all as regularly updated Docker containers.
