Pik tv has moved the on-demand episodes of the Discovery Gold Rush series over to Crave tv for some reason. Why? These used to be available with my Discovery Channel subscription, but without a subscription to Crave they can’t be viewed.
This seems like somebody made a mistake, I expect they are still supposed to be part of the Discovery n-demand service.
I am still seeing Gold Rush as being available through On Demand through Discovery on Pik TV. I don't see Gold Rush available on Crave at all, even in the Crave app.
How are you trying to access Gold Rush? If you go to Pik TV --> On Demand --> Channels --> Discovery --> Gold Rush, are you able to watch? Or are you searching by title?
Update: it seems like our quality assurance team found the problem you described this morning, and fixed it before Nighthawk and I had a chance to check. Let me know if it's still not working for you.
