The app builds a large buffer (like 20 minutes) before playing an episode. This is good when on Wi-Fi or unlimited mobile data but a big problem on limited data plan. For instance, when discovering new shows, I just want to play the first couple minutes of the 1st episode to see if the show is worth subscribing to. Then the app will try to fetch that large buffer and after trying a few shows I've already used hundreds of mb. A solution would be limit that buffer to 3-4 minutes on mobile data or add a separate option for that in the Network setting.
