Like others, I had lost unlocked episodes. Following the advice from another reviewer, uninstalling and reinstalling, and then using the "Restore Purchases" option succeeded in recovering all my unlocked episodes. But I have to do this pretty much every time. This issue aside, the app would otherwise be great. My two year old girl loves to watch her favorite episodes, which can be pre-downloaded to save on bandwidth, especially while away from home. She also loves the Talking Pocoyo app.
