Make the mobile push notification continue to make a sound just like the alarm!

First of all, I think it's already better than the 2.5x more expensive ADT equipment I bought several years ago because I don't even think the app makes a sound when the alarm goes off. It just gives me a notification and that's it. At least SS sent a notification AND a sound. But it does this only once. That makes no sense to me.

The alarm on the control center sounds for up to 8 minutes and yet my phone will only make a sound once. So I better hope I have my phone with me a the moment the alarm goes off, or else remember to always look at my phone if I've been away from it.

Perhaps it is a limitation of the phone's OS and notification system, but the app should continue to send a sound notification for as long as the alarm is going off or until I interact with the app, whichever is first.
