I have an iPhone 8 running iOS 11.4.1 and I have run into a rather annoying problem with the Messages app that I can't seem to remedy. My wife has an Android phone and I'm finding I am no longer receiving SMS notifications sounds when I receive a message from her. I have checked to see if her contact or the phone has been set to "Do Not Disturb", but it has not. Sometimes I get the notification sound and the screen lights up as expected but it seems to happen only when I receive an SMS from an Android device. Whenever I receive a message from a iPhone it works everytime.
Anyone else run into this problem?
