Android Mobile App - Missing Channels by Category

[campanaa]

Although I can see the full TV guide on both Apple TV and my Android mobile, if I switch to a category on the Android mobile such as News, I don't see any of the channels within that category:

I get a similar message if I look at other categories such as Sports, Drama and News.

How can I restore the channels by category?

Thanks!

What version number is shown inside the app settings

Should have done this first before posting. I've just uninstalled and then reinstalled the app - it now works!
