ESIM: Always taken to unknown state for iOS 14.0, where it work perfect for iOS 13.0

I work for one of the networks. I am able to successful download the eSIM in iPhone for iOS 13.*.

Where I was taken to unknown state (CTCellularPlanProvisioningAddPlanResult) in iOS 14.0 always also it prompt the os screen to install eSIM("Set up Mobile Plan")

Please let me know why it take to unknown state always and why OS screen popup ?, please let me know if any configuration needed specific for iOS 14.x

Also attached the configuration & prototype code for your reference

Code Block  if #available(iOS 12.0, *) {
      hud.show(animated: true)
      let plan = CTCellularPlanProvisioning()
      self.request = CTCellularPlanProvisioningRequest()
      self.request?.address = "" // SMDP Address
      self.request?.matchingID = ""  // Acitvation code.
      if let validRequest = self.request {
        weak var weakSelf = self
        plan.addPlan(with: validRequest) {[weak self] result in
          self?.hud.hide(animated: true)
          switch result {
          case .success:
            weakSelf?.alertMessageToUser(title: "Hurray !...", message: "ESIM Downloaded Successfully")
            print("Successful")
          case .fail:
