I recently converted my app to be able to run on Fire devices. I am using ADM Messaging to receive messages and then create notifications as per the ADM docs, so that users receive alerts when the app is not in focus.
When I minimize the app I receive notifications and everything is working fine.. until I leave the tablet alone for a while and it goes to sleep. At this point if I trigger a new ADM message nothing happens.
If I then click the power button to wake the device, I get the notification.
On a device running Fire OS 126.96.36.199 when I wake the device I hear the notification alert sound and see the notification.
As per the docs, I have added the WAKE_LOCK permission to the Android manifest file, which I assumed is required to prevent this issue, but it seems to have no effect.
Any help would be gratefully received.
