Being able to be alerted to critical situations like weather alerts is crucial, and I don't want you to worry about this going forward. Granted this alert is not sent out specifically from us, there are underlying factors on how these messages get sent. There is a targeted area with the alerts which dictates who gets the messages, and based on the location of the device and the tower they are connected to; they would then receive the alert(s).
Where were the S7's in comparison to the iPhones on the account when the alerts were received? Have your S7 devices ever received any Emergency Alerts in the past?
Check out this great link (questions number 10, 11 and 18) that give more detail surrounding why the other devices may not have received the alerts. http://spr.ly/6586D5ftM
Does this help clear up the details?
