I don't use the app, but if it is happening on both the phone and iPad I would suggest it's something with AppleTV or the app. Unplug the AppleTV to give it a reboot. If that doesn't work it may be a bug in the current version of the app.
Edit - Looking at the recent reviews in the app store it seems that the latest update killed swiping to navigate and scrolling, only finger presses work.
Thanks Jim. Whati find strange is that I had been using it with no problem for days and weeks. In fact, the last four days I've used it hor hours at a time looking at YouTube trying to decide to purchase something. And when it quit id been using it for a couple hours straight then it quit.
If we don't count our blessings We are just wasting our time
