I like to have the Android app on my phone to notify me when it's my turn etc.
I've recently upgraded my phone, and although I get the notification, I only see it when I'm actually using the phone. If it's asleep, I don't see anything, and in neither case do I get any sound (all of which kinda defeats the point in having notifications!)

Notifications seem to be setup correctly on the device, and I have enabled sounds in the Warlight app, yet it doesn't work.
This is Android Marshmallow.

Any thoughts?
Thanks.
