I have been frustrated by this problem for a while, but an answer given above by RamblingC has helped greatly.
Even though sometimes it reoccurs, using a long press on the exit button fixes it every time and I can now use the app consistently.
Same Problem here with a Samsung UE55JU6800. Even using NowTV on my Playstation 4 Pro, seems to be lagging in the Navigation menu. It just works because of its sheer computing power but even then, it's slow and buggy. Who wrote those apps?
I have the same screwy menu problem as others. My TV is the UE65KU6400.
This in a NOWTV forum and in 2 months no input to this discussion?

Gone again 😞 I have no control over any function you press on something and something else comes up. When I try to hard shut down as soon as I press exit it's gone. I give up.
I have reinstalled the app - works fine for a while
Turn TV off at wall - works fine for a while
Amazone Prime - works fine all the time
BBC iPlayer - fine
ITV hub - another story - other forums
A note to all...
If running the NOW TV app on Samsung televisions is anything like running the NOW TV app on LG televisions, it's vital that your televisions software is the most up-to date version.
I have this problem too; I can't quite believe there's been no positive response from the provider. This is a clearly a coding issue, and should have been an overnight fix for the development team.
