help with tubi app and IOS14.1

I went into the tubi app, free tv shows and movies... I chose a show, the show spellBinder, it only shows the first three episodes. I turned on screen recognition and then when swiping back and forth and scrolling the screen I got to some later episodes, but I am not sure how and the behavior seems inconsistent. How do I propperly scroll in the tubi app to choose a particular episode of a show?
