FCM - Android stops receiving push notifications

[Cristian Merli]

Hello,

I've been using FCM to send push notifications to iOS and Android devices successfully so far, but I have one issue on Android: android stops receiving the notifications after a few hours without using the app.

To test this, I set up a scheduled task that sends a push notification to my iOS and Android devices every 15 min.

Then I close the app on both devices and never use it again, I just monitor the push notifications.

• iOS keeps receiving notifications every 15 min accordingly
• Android receives them for a few hours (3-4 as far as i can tell) and then it stops. Notifications are still being sent, but not received by the phone
• If I open the app on Android once, then I start receiving the notifications for a few more hours and then it stops again

Is it a known issue? What info can I provide to help troubleshoot this?

Thanks
