Hello, i've got a HDHR4-2DT homerun device, i'm using app channels for hdhomerun standalone app on two apple tv 4k and i systematically get the error "All tuners in use" when i try to change channel while i'm watching something else on another device.
I noticed channels app, since latest updates, tries to use a different tuner every time i change channel, but i think this leads to an error if one tuner is already used by another device.
I've started having this issue since november, had no issues before, and if i try the official hdhomerun app i get no issues at all as any channel change is done on the same tuner.
