It seems like anytime I try to use home sharing on my 4th gen apple tv, when I click on the computers app, it doesn't show my computers. Just gives me the message to turn on home sharing on my computers. If I then go into the settings on the apple tv and turn off home sharing, it says it is on. If I then turn it off an on again, it works for a while, then stops working again. Is anybody else seeing this issue?
