If you have iOS and install the Fox Sports Go app, you may see error “Could not create registered Session” when starting the app. You will also notice that the error doesn’t go away by restarting the app or restarting the device. Here is the fix
Unfortunately, the error doesn’t really explain the problem. The error is caused because the user (that means you) does NOT have location services turned on for the device. Location services aren’t specifically listed anywhere as a requirement but it seems that they are. So if you go to settings -> privacy -> location services, turn that on, then start the app (or restart if it was already open) you will find that the program seems to work just fine.
And once you start Fox Sports Go with location services on, you will find that the app works just fine.
