are we missing something?

this has to be the worst app I've ever experienced. Crave constantly forgets what episode we've last watched and we're forced to fast forward through multiple episodes to get back to the episode we actually left off at and then half the time crashes and forces us to watch 4 more ads. is there a way to fix this? we're watching through our smart TV which has no issues with any other app. for example, we're watching 'the leftovers' and finished off on season 2 episode 8. when we go back to continue the next night it'll load up on episode 6. and then the next night we'll finish on the first episode of the next season, and it'll run back to episode 9 of the previous season. the worst part is you cant even select what episode you want to watch unless you physically go to the home menu and search the name of the show which is a pain with a tv remote.
