Hello There,After upgrade to iOS-13, we are unable to receive Device Token (intermittent) when we performUIApplication.shared.registerForRemoteNotifications()neither delegates calling back.application:didRegisterForRemoteNotificationsWithDeviceToke application:didFailToRegisterForRemoteNotificationsWithErrorWe are performing all the operation on Wifi network So here strange thing is all is working fine with iOS-10, 11, 12 however not in iOS-13 so we are kind of blocked here, Also assuming there must be some improvement/ modification that is causing the issue.We have tried Restart/Reboot device, Disable/Enable and Change network connection and found its working (intermittent not 100%) however this is not the actual solution of the problem. User perspective we can not force the user to Restart/ Reboot the device.
