VOIP Push token not being generated on TestFlight

Hi,


In my ios app, i have created a VOIP push certificate and have integrated PushKit, in development it works fine, but on TestFlight the app does not generate the token. I have tried deleting and regenerating the certificate and restarting the iPhone but no matter what i do, the token is not being generated on TestFlight.


I have only implemented voip push, not apns if that makes any difference.


Xcode version: 10.2

iOS version: 13.2

iPhone: iPhone X



Thanks,

Akil
