I get the same push notification twice in iOS 9, but it works fine in iOS 8.
The problem still persists after updating the iOS version to 9.1, 9.2. The application generates new device tokens each time the application is uninstalled and reinstalled.
I found a solution that suggested saving the last device token identifier marked by the user and deleting all previously marked device tokens, but I want my user to log in to the application from several devices (for example, iPad and iPhone), so I can not execute the solution .
Any possible solution / tips to solve this problem?
