Sometimes things can go wrong. There can be many different reasons why your app is not working.
Please, remove the app from your iPhone/Android, restart your device and download it fresh from the App Store/Google play. We recommend that you connect to a strong and stable WiFi connection instead of doing it over 3G and 4G
