If you have successfully installed the app and you are not able to see any content when you click the "Play" button there are three things to verify first:
Are you using one of the supported Devices below?
Do you have an active Internet Connection?
Is your internet working properly? This is important because a Wi-Fi signal might appear to be working but not have any connectivity. Try opening other web pages and testing your connection to verify other apps are able to connect. Without an active internet connection you won't see a playback button on the FYC App because the app will be in "offline mode." You will still be able to see movie titles and descriptions but you won't be able to playback content unless you have already downloaded content for offline viewing. If you are using your cellular connection there is a chance it is having connectivity issues which could result in poor performance.
Quit App and Relaunch
If your internet connection is not the issue then please try quitting the app completely and relaunching it. Please refer to your devices directions for quitting and relaunching because directions can vary depending on what type of operating system you are using (MacOS vs PC vs Android) or what hardware you are using (Phone vs Desktop).
If you have tried the suggestions above and are still having issues playing back content then please contact support: http://fyc.wbtv.happyfox.com/kb/article/25-how-do-i-get-support-for-the-fyc-app%20.
