I guess the question is if you can install the Patreon app or watch through a browser on Google TV? I've been watching via AirPlay from my phone but it keeps crashing and disconnecting so I'm looking for another solution (and yes I have dedicated several hours to troubleshooting without success).
If no, are there any other solutions that might work? I've been thinking of buying Google TV anyways, is it worth it?
I don't see where the app is compatible with Google TV. You could try the TV Bro app and see if it works for you. Basically a TV remote optimized web browser. The other option would be to download them and either copy to USB and play using VLC or similar or run Plex/Jellyfin locally on a server.
