I use to be able to watch ABC Live via the App and now all live shows are locked. I have Comcast as my cable provider. Was there a recent change with streaming Live ABC via the App? Not sure if it is related, but the ABC app has always given me trouble. e.g. The live streaming section would show "not available" and the only way to fix the issue was by restarting the Apple Tv 4. Anyone else having the same issues? Thanks!
