Thanks for letting me know - I watched half the Crusaders game last night but today it has disappeared from the list of games! Highlanders v Blues & Moana Pacifika v Fijian Drua still have only static.
Same problem here with 3 games, Highlanders v Blues, Crusaders v Chiefs & Moana Pacifika v Fijian Drua. Reds v Hurricanes & Force v Rebels are both ok. I tried it on both ipad & my TV so it's clearly a technical issue at Sky.
