So I'm looking out for an Amazon delivery I don't want to miss, and the Amazon Shopping app puts up the message in my phone's notification area saying my package is 6 stops away, view it on a map.
But the notification makes no sound, so chances are I don't notice.
Similar to this question about Google Calendar notifications misbehaving in the same way. There are no answers to that one to date, and the person fixed it eventually by reinstalling the app. But I've already tried installing the Amazon Shopping app on three different Android devices (Samsung phone, Motorola phone and Amazon Fire tablet). On all three devices the issue is the same.
I've checked all the related settings I can find, both general Android settings and those within the app.
How is it possible the Android operating system can let the user configure audible notifications and it all works fine except for one app?
