Hi saviour1,
Thanks for your post and welcome to the forums. It's really great having you on board with us in the Community.
I'm sorry to hear that your viewing has been interrupted through the Sky Sports App on your iPhone. As it's been working until recently, have you changed anything on your iPhone that may have knocked something out? Such as have you ran any updates to your iOS or has the app updated?
When loading Sky Sports, do you go through TV Go or do you open the Sky Sports app directly?
Can you try deleting the app from the iPhone and reinstalling it to see if this helps resolves things?
Pop back and let us know how things go.
Thanks,
