I am using 10.6.0 on a W10 server, the latest android app and an android (8.10) phone on a decent 4G signal.
When playing (flac) music files, playing will suddenly stop. It can often be re-activated by just turning the screen on. Quite often the screen will be dead (i.e. pressing pause/play will do nothing) after activating the screen. You can however back arrow and the interface is useable.
I thought it might be the sleep setting after 2 mins. I have turned off battery saving for all apps and set sleep to 30mins. So far I am not clearly noticing consistent effects.
