In my last version of my Application I used Appoxee to send push notification and in my current version, I wanted to switch to UrbanAirShip so I removed Appoxee from the code and integrated UrbanAirShip.
Now when I upgrade the app, I still receive the push notification from appoxee. I want my old users (using old version of my app) to receive push notification from appoxee and new users (who is on my latest version) to receive only from UrbanAirShip. How to unsubscribe push notification from first vendor
