Sky sports app issues

I have been watching the football on my iPad. The full first half was fine, and with my battery low, I turned off for half time and switched back on for the start of the second. 
however when I did, it wouldn’t work. It would only say apologies, we can’t load the page at the moment. 
other channels with play and work, just not any showing the football. 
it does however work on my iPhone, which is the same subscription.

I’ve deleted and reinstalled the app, no success. This also happened last night with the football but worked once I reset the app.
