But the apps don’t work now. Before the error, they did. So that error is affecting more than just music streaming.The error comes from the audio system. Go to "media" click sources, the Media streaming source is the cause of the error as it cannot connect to the streaming sources. It cant connect and assumes you have consumed all your data allowance. Why it needs to tell us, constantly, even when that is not the selected audio source, is beyond me.
So the error is a result of a connectivity issue that affects certain features of the entertainment system.
