Some push notifications aren't being delivered

Android

Backendless Version

backendless: 5.9.4

Behaviour

I’ve tested sending the notifications using the Backendless panel and the API method. I don’t have a great sample of devices, but there was some strange behaviours.

The notifications were delivered as the expected to almost all devices by the 2 methods. But in 3 of them the devices only received the message generated by the API and 4 of the devices didn’t receive any notification.

The coincidence in this group that didn’t receive any message is 3 of the devices are Samsung with Android 10.

I’ve saw some recommendations in others topics like adding “android-ticker-text”, “android-content-title” and “android-content-text”, but this didn’t make any difference.

The count of Push Messages in the panel increased after the command showing that the message was sent, the question is only to understand why is not reaching all the devices and if there is any acessible log to verify.

Hi @Roberio_Lima,

Could you please send a push notification targeting specifically a device where it previously failed and after you send a push notification use this API to check the status of delivery?

Hi @mark-piller,

I sent to one of the those failed devices and I received this response:
{
errorMessage: null,
messageId: ‘message:C450D68C-B90C-4233-AEFE-F74B2843E0B6’,
status: ‘scheduled’
}

I tried 3 times using the axios of the node.js and I received the same response:
{
errorMessage:
‘Could not find status for message with id: message:C450D68C-B90C-4233-AEFE-F74B2843E0B6’,
messageId: ‘message:C450D68C-B90C-4233-AEFE-F74B2843E0B6’,
status: ‘unknown’
}

Hi @Roberio_Lima

I tried my best but I couldn’t reproduce the issue.
I tested different approaches:
via Backendless Console and via API. With real and emulated devices. With different Android versions.
Also I tested push notifications with real Samsung device with Android 10. Everything works fine.
I can suggest you to reinstall the app on your devices. Sometimes cache can be the cause of the problem. Also you can clear the RN cache by running

cd android
./gradlew clean

Hope it helps you.

Thanks, @Maksym_Khobotin!

I’ve already did this gradlew cleaning process a lot lol
I will try to send the notifications again even because I couldn’t too reproduce this issue in my devices.
It was something related by some users that tested the app. Maybe is somekind of conflict in my app and the Android version of those devices specifically.
The difficult part is discover what is

I think it can be some kind of regression.
I would recommend your users to reinstall the app.
