Their awful UI is an artifact of trying to be a storefront (where shows are sold by the season) and a streaming service (where you can binge without regard for seasons).

This might depend on the device, I'm using the Fire stick and I think it bundles the seasons under one show.

I'm not praising that app at all btw, that's just why I think the award for worst app goes to CBC gem on the Fire stick. It shows you which episodes you watched. Past tense. To watch the next one you have to search for the show again and navigate to the episode. Why on earth would anyone want that?!
