Hi! I have bought a pair of ls50 w2. When I use them via AirPlay (not sure if I can also trigger the issue with Bluetooth) after some hours of using them, they do not play anything via Bluetooth or AirPlay anymore. I can still connect but I don’t hear anything. I also can not use the tidal integrated app anymore. When trying to play a song in there I get an error:stopping playback. I still can use the coax port and it works fine. I can not solve the issue with pulling the Power cable. When I reset the kefs it works fine again - tomorrow morning I realiced that also if I let it sit there over night, it works fine again...... Do you have any ideas or similar issues? Thanks!
