Hello, I am trying to utilize the Critical Messaging API to allow my user to message 1 or multiple pre registered contacts automatically. An issue I am having with this in testing is that when the application attempts to fire off texts to the phone numbers the success rate changes from trial to trial, with no variable changing. Sometimes I can send a Critical Message to multiple phone numbers in rapid succession, sometimes the message is only sent to 1 contact, and sometimes I get no successes. Each failure always returns the MSCriticalMessaging.notSupported error. The API documentation states, "The send(_:to:) method only works if the app is backgrounded, if it’s called from foreground the framework returns a MSCriticalMessagingError.notSupported error." If my app is always backgrounded in these tests, what other issues may cause this notSupported error return, and why does the outcomes success rate vary?
