Can't seem to watch Dave live on Roku UKTV Play but can on phone?

[Hades]

I'm not sure whether this should be in the Home Cinema forum or here. I have the UKTV Play app on my phone and can watch their channels streamed live, including Dave. But when I use the UKTV Play app on my Roku I can't see any option to stream live.

Am I missing something obvious or is live streaming not available on their Roku app?

Thanks.
