Volumio frequently looses my (different) DLNA media servers offered via internal network since updated from 3.324 to 3.378. „Loosing“ means, the servers are offered after starting Volmio, playing some tracks, but are lost for next browsing. Sometimes they are reshown after a restart, but frequently also not. Tracks in the queue keep playing.
This happens on my primo and also on my two raspberrys. All are connected by wired network. Nonetheless music can be send from the media servers to all Volumios by an general player app.
