@Jodie-jo Welcome to the community. A couple of other people have posted the same issue (altho in their case on Apple TV) and it has been reported to NOW TV to investigate so hopefully they are working on it. However I'll tag @Mary-E @Ian-H from the NOW TV Team to make them aware, they can make sure someone is looking into it.
Been trying to replicate the issue but channel is playing out. Can i confirm you're using a NOW TV smart box?
Does this happen when you're trying to watch boxsets? It might be a particular way of navigating that's causing the issue, which will help us fix the issue.
This started happening to me a week ago. Am using nowtv via Apple TV. If I click to show schedule comes up headed sky living and very often shows for 3am 4am 5am when I am trying to watch at 8pm. Click on a show goes to a purchase page. Come out of this and go back in will show sky witness but again timings for 3am 4am etc but click on top listing will show what is live but I can’t find out via schedule. A bit of a palaver. Was really good previously- name changing never seems to go well for any organisation.
so I’d say it is not playing fine
