I am running iOS 11 with the latest BI4 on the server and BI4 on the iOS app. I have two devices my iPad receives the triggers and the alert tone. On my iPhone I am not able to receive the alert tone but I do receive the trigger and the picture associated with it. I have notifications turned on for audio and my phone is not on vibrate. BI4 shows both devices checked in the option mobile config. What’s going on?
