I have two Pi systems using PiCorePlayer. The main system runs LMS. They used to sync without a problem and if I switched the slave system on, it would play whatever was on the main system without intervention from me.

For a while now when I switch the second system on, it now stops the main system playing. If it has a single track or radio station, it stops on that. If it has an album, it goes to the last track and stops. If I restart whatever was on the main system the slave syncs and plays.

I've tried setting sync up from both players without any change. Is there something I'm missing?

LMS version is 7.9.2. PiCorePlayer 5.0.1. Using the Material skin.
