Firebase notification not playing sound on iOS

manpreet Best Answer 2 years ago

_x000D_ Turns out there is a bug in iOS. For me, I had originally set my app up with an incorrect fcm messaging option for sound. This ineffect meant I was sending notifications without sound. Once I had corrected this fcm setting issue (using the format as indicated in the referenced link in my question), I still had no sound. The fix was to go into the iOS notification settings for my app and toggle “sound” to off then on again. Problem solved.
