Message not received when app is in background mode

[Sathishobs]

Problem in background mode. When the app goes background state Receive message is just stopped and no further updates from peer. It gets active and returns the older messages when I become foreground. This is stopping my integration and looking for alternative SDK. Am I missing anything around to config? ( enabled all background config under capability )

iOS apps cannot stay alive forever in the background.
To wake your app send use APNS.
