On my Shield 2015 with latest non-hotfix firmware and updated apps, Live Channels sees Pluto as a source and loads guide data but when I try to watch a channel I just get an infinite blue loading circle. Tried uninstalling Live Channels and Pluto, granting permissions to Live Channels, etc., but nothing seems to work. I'm about ready to try a factory reset on the Shield. Anyone else experiencing this?
The last Live Channels update doesn't play well with Pluto for us. The guide info kept disappearing, and we also occasionally got the spinning circle. I just uninstalled the most recent Live Channels app update through the Play Store and it works fine now. You have to turn off auto updates though, or the app will just update again. I think Pluto needs to push an update to fix it, because our other linked apps work fine in Live Channels.
