I am not receiving notifications for my activities. What do I do?

When an app is in a "Force Stopped" state, the push notifications will not be received.

An app might have been placed in this state in the following ways - 

• From Settings > Apps, "Force Stop" is pressed
• Long pressing the back button on some devices
• Using a 3rd party task killer like Greenify
• Swiping away your app from the recent apps on the list on a Xiaomi device
• Automatically on some devices due to custom Android tweaks done by manufactures
  
  

The issue can be rectified in the following ways -

• Asus -
  Check your app in the Auto-start Manager
  
  
  
• Huawei -
  Step 1: Settings --> Advanced Settings or Power Saving --> Battery Manager or Protected Apps --> select the app to protect it.

  Step 2: Settings --> Apps or Notification Manager --> Advanced or Notify for your app --> Ignore Battery Optimizations, select the app and ignore it.

  Step 3: Settings --> Notification Panel & Status Bar --> Notification Center, select the app, then activate "Allow Notifications" and also "Priority Display"
