I'm to trying to test my push notifications while utilizing TestFlight.
I can successfully receive a push notification on a device when I deploy directly to it from Xcode. However when I deploy the app to the device via TestFlight (as an external tester) I get "BadDeviceToken".
I have created a "Universal Push Notification Client SSL Certificate" and followed these apple instructions to the letter (I think). As per link:
"The client SSL certificate that is generated is a universal certificate that allows your app to connect to both the development and production environments."
Has anyone got any ideas?
Thanks
