Sky ROI sub for Variety pack, trying to watch Ice Road Truckers Series 8 as listed in the catchup TV section for History channel via Sky Go PC. All of the series 8 episodes are listed in catchup
Watched episode 1 fine, but when attempting to watch any subsequent episode in this series I get the dreaded "You will need to be a Sky TV customer with the relevant pack to watch this programme." message.
Am I correct in my understanding that if something is listed under catchup for a channel included in my variety pack then I should be able to watch it, irrespective of whether or not it's also listed as a box set ?
