No notification sounds while on Data

I did all of the above but still not working.   Also, my Rogers home security system sends notifications including sound while on wifi, but no sound notifications while on cellular either.   I can access the sensors while on cellular and see that door sensors triggered show up but no sound notifications.   I get text notifications with sound.  Wonder if its the Xfinity gateway not sending out sound notifications even though it was setup for push notifications.  Rogers said to contact phone provider.
