We have a firestick 4k on our bedroom TV that we watch for a couple hours at most at night.
I've started getting a "tuner not found" when we change channels after watching for about an hour. When I go to my pc (which is the channels server) and go to watch or change channels they all work normally.
I thought it might be a cache problem so I went and cleared the cache for the Channels app and presto, it works again.
Anyone have an idea how to fix this, other than clearing cache every time it happens? My main device in the FR is a shield and it's never happened on that.
