By default, this configuration is on. PUSH notifications in Android is a technology working on the system level and can receive messages sent from your server, and reduce energy consumption.
 
In MyChat such the notifications are encrypted and sent from your server to the gateway for sending messages on the developers' server. Only the recipient can decrypt such messages.
 
PUSH messages are sent to the mobile application if only MyChat Server has access to the gateway on the address "https://mychat24.com:52020", and if the internet is available for mobile applications.
 
If for some reason these conditions are not convenient, disable this configuration for PUSH notifications.
 
Disabling this configuration changes the connection to the server — the application starts connecting to the server via TCP port, specified on the Admin Panel, and not to the  WEB server. Also, the application attempts to work in a background mode with the constant notification that the chat is running.
 
As the application constantly connects to the server in a background mode, your OS may consider it resource-intensive and deletes it from the memory.
 
We do not recommend disabling this configuration if there are no real obstacles for PUSH notifications work.
