Additional context

[CicoZhang]

only after manually restarting the liquidsoap service, it takes effects immediately.

[fast97]

Yes it is effectively by restarting liquidsoap that the programmed playlists work.

[CicoZhang]

Yes it is effectively by restarting liquidsoap that the programmed playlists work.

As log shows, it works in the following day, and I will test it tonight.

[SlvrEagle23]

This is unfortunately by design with the "Advanced AutoDJ configuration options" in playlists. Since they're managed by the Liquidsoap AutoDJ and there is no way to reload Liquidsoap configuration without actually restarting the Liquidsoap service itself, this is a necessary component any time you make changes to a playlist with those settings enabled.
