I have a WiiM Amp with 4 playlists set up each containing around 75 tracks on a WDmycloud nas. They were all playing fine but now when I click on a track to start the playlist it will either skip through the playlist without playing anything and just stop at a song down the list or it will start playing a different track that’s not in the list. All the songs play fine if I just play them through the music share button. I’ve tried rebooting and rebuilding the DLNA database and the problems still there. I’ve started a new playlist using some of the same songs and it’s fine at the moment but I’m reluctant to redo all of them if the same thing’s going to happen again! Any ideas please?
