Can Alerts be Pushed to More Than One Smart Phone

New Simplisafe installed.  Trying to figure out how to configure it.  I want my phone and my husband's phone to be able to monitor the system.  We both installed the mobile application on our respective phones.  We are using the same id to login to the mobile app as I was told by SS support that two diff users could not view the same system.  So we have one account for apps on each of our phones.  I have configured email alerts to go to both of us.  But I can't get his phone to allow push notifications.  The work on my phone.  Push notifications do work on his phone for other apps.  He has iPhone 11Pro. From the mobile app on his phone, I go to Settings, Notifications, SS app and "allow notifications" is on as are all three alert types.  Banner Style is Persistent.  All of this is the same as what is on my phone.  But from the SS app on his phone,  push notifications says, "Push Notifications from Simplisafe are Disabled.  Please go to your phone's settings screen to give permission."  

Is SS app able to have push notifications sent to two diff phones?  Does anyone else have this working?  It would be a shame if only one phone can get alerts!  Any help is appreciated.  Also, how do I search the forum for a topic similar to this one.  I didn't see a search bar for me to type in a question.
