I'm running older hardware with Channels and have not run any issues until recently. I'm now having problems with signal. It seems to be only occurring within the Channels app (Plex works fine, as well as direct from antenna to TV). I actually replaced my antenna over this, thinking it was failing. My next move will be to replace the Homerun, but I'm not thinking this is the issue (although I could be wrong). I've also re-installed Channels, restarted Apple TV, and I'm still having problems with reception.
Does anyone know if changes were made to the app recently that may be causing breakage with older Legacy tuners?
