I am trying to implement silent push notification in my application where I need to update some data in the server when silent notification comes. I am using Pushkit and it uses VoIP certificate for silent push notification but the app has been rejectd by Apple saying that "I can't use VoIP" certificate. It seems that apple has rejected it as I don't have any VoIP call functionality in my app. In that case how can I implement silent push notification so that my app gets activated even if it is not runnning(not even in the background) and I can update the server?

I have purchased a redemption code from my ABM, Now I am distributing the code/link to my users. As my end user's are around the world. User's are from different countries are getting error message while redeeming the code like "the code is valid only in India store!" What's the solution for this situaion.
