I have the latest app version 2.04 on PS4.
I click on watchlist and any TV show I click on to load up the episodes to watch, it just spins the loading screen and I have to then restart the Now TV app - same thing happens. The only way I can load up the episodes screen is by searching the show manually and it works that way. However this this is time wasting.
I have the same problem that's been ongoing for a few months.
It's the view all section of the watch list that's not loading but the short version of the watch list just below continue watching is fine.
