Does anyone else have this problem? I have Pluto, Haystack, and HD Homerun installed and set up on my 2015 Sony UHD TV (55'' 850C or whatever, the one that got the HDR update). The other day I tried to use the Live Channels app (or the Sony equivalent of it, I forget what they call it) and it's stuck on one of the Pluto channels. I can't get the channel guide to show and I can't get it to change live channels. I've tried all the directions, the select and channel buttons. I'm pretty sure I remember that when in the app the ch+ and ch- buttons would change the channel like when using the built in tuner. I tried restarting the TV by unplugging it and when it rebooted the problem was still there. I've tried using both remotes and the Android TV remote app and non of them seem to be able to bring up the UI.
I also have an Nvidia Shield that I use with this TV but I'd still like to get my app back to working correctly. Does anyone else have this problem or know what I can do to fix it?
I don't actually own an Android TV at the moment so am not sure what you can actually do in the app settings, but on standard Android if I had the same problem I would go into the app settings for the Live Channels app and force stop it, then delete the cache and app data. You might have to set it up again to your liking afterwards. If that doesn't work then I have no idea.
