Hello @Ayaz_Khan
Unfortunately, I was unable to reproduce your problem.
We will be happy to assist you. I need to ask you a few more questions so I can understand the problem better.
Is operatingSystemVersion = 1.0 in your real devices?
Did you make the setup according to this documentation - Push Notification Setup (Android)?
Is your Android application downloaded from the code generation section (Console-> Code Generation-> Category: Android-> Push notifications)?
What does your AndroidManifest.xml file look like?
What does the code that should receive the notification look like?
When you send a push notification from the console, do you press SEND NOW button (Push from Console)?
What is your template for sending a notification when you do not receive a notification?
Could you provide a minimal project in which the problem is reproduced (your project in which there is only device registration and receiving push notifications)? This could greatly speed up the identification and resolution of your question (Share secret data with Backendless team ).
