I got catch up back on the screen by doing a factory reset. It worked on my smart tv, but not on my old tv. I have no clue why, but glad i have got catchup back on one tv.
try doing a factory reset on your now tv box. It worked on my smart tv, and catch up came back. Didnt work on my old tv though. I think its a software issue.
I asked them via the online chat, and they suggested a few things that didn't work. I did a factory reset on my nowtv box, and got catch up back on one of my tv's, but did the same on the other, and it didn't work, so not sure whats going on!
