VOD stops playing on Android app

We weren't even offered the TV box, so we've been trying it out on our phones.
Both my boyfriend and I have been watching a vod tv episode and it just stops and jumps to the home screen after about 11 minutes? I'm on Android beta 10, but he's on Android 9 and runs everything stock so it isn't that!
I found a post from 2017 expressing the same issue. So far, I'm really glad this is free.... Cause if I were paying for it, I think I'd be unhappy!
