When connected to the WiFi my phone app doesn't work. Everything else on my phone works I I know the Internet isn't the issue.

Hello Prestontreeandga, thanks for posting on the Community page, can you please try fully uninstalling and then reinstalling the same, see if it then works the app for you. 

Thank you, I have just done it and the problem is still there. When I turn off my WiFi the site loads fine. all my other apps work fine on the wifi.
