Hello and welcome to Android Forums. Hopefully I can help you with your problem.
The app you are using may need to have the cache and data wiped or the app may need to be reinstalled. Personally, I would reinstall the app then make sure are setting are configured correctly.
You can also try another 3rd party app from Google Play. Make sure all the settings are configured properly.
If you have any other questions regarding your device, I invite you to join Android Forums. We have many sections for specific devices which contain a wealth of information.
