NEVPNStatusDidChange Observer is not updating correct time when app is in background

I am using

NetworkExtension

and creating/managing a

Personal VPN

configuration that uses

IKEv2

built-in VPN protocol.

When I connect the VPN from my app it give me

connectedDate

from that i am getting time stamp to show the timer like 00:00:00 which will start when the VPN is connected

After connecting VPN I put the app in the background, Then I open the settings app and I disconnect and connect the VPN again from the General->VPN. After that when I open the app again the

connectedDate

I am getting is still the same(first time VPN connected).

My VPN profile is configured successfully and I am calling

loadTheVPNPreferencesOnly()

in

applicationDidBecomeActive

func loadTheVPNPreferencesOnly() {
  NEVPNManager.shared().loadFromPreferences { (error) in
  if error != nil {
  print(error.debugDescription)
  }
  else {
  print("No error from loading VPN viewDidLoad")
  }
  }
  print("adding NEVPNStatusDidChange Observer.... ")
  //OBSERVER TO CHECK THE VPN CONNECTION STATUS....
  self.addConnectionObserver()
  }

I also tried like this, But the

connectedDate

is still previous one:

let VPNConnecteddate = NEVPNManager.shared().connection.connectedDate
//print(VPNConnecteddate as? Date) // 2020-01-30 14:46:56 +0000
let VPNTimeStamp = VPNConnecteddate?.timeIntervalSince1970
if VPNTimeStamp != nil {
  CommonMethod.saveUserDefault(key: "vpnTimeStamp", value: VPNTimeStamp)
  print("VPNTimeStamp===> \(VPNTimeStamp)")
}

I will really appreciate if someone helps me on this point. I have searched a lot for checking this online.
