Notifications

Summary:
The first load of an app with local notification custom sounds works correctly. When the app is updated (by Xcode, TestFlight or App Store) the app plays only the default sound. Behavior is the same with either new UNUserNotifications or deprecated UILocalNotifications. Behavior only occurs on iOS 10. The custom sound is a 2 second caf file in the application bundle (and it plays correctly multiple times until the app is updated). Notification permissions including Sounds are properly granted. Deleting the app and reloading causes the custom sound to play correctly again.

Steps to Reproduce:
1. Install original app
2. Update app via Xcode, TestFlight, or App Store
3. Send notification

Expected Results:
Custom notification sound is played

Actual Results:
Default notification sound is played

Version:
iOS 10
