Selecting an episode returns me to the main menu.
Try these three separate solutions.
1: Clear the cache. You can do this by opening your device’s Settings app, navigating to Applications > République, then selecting the “Clear cache” button.
2: Restart your device (turn it off then back on again, or select the “Restart” button after long-pressing the power button).
3: If neither of the above fix it, you may need to re-download the Episode. Unfortunately, the data occasionally gets corrupted and can result in the Episode not loading.
