Is there anyone Who knows why the Mac (used as roon core), when enter the screensaver (‘cause you were not using it) don’t allow to open again the app on the phone or tab? You need to move mouse and re-enter the desktop of the Mac!
Thanks for the help.
Simple - your Roon core Mac should never sleep, or you need a reliable way to wake it beofre playing… like wake on network access. But I found this to never work, so I leave my Mac on all the time.
