I'm trying to get push notifications on an app that's using Twilio IP Messaging. After following the instructions that I can see here: https://www.twilio.com/docs/api/ip-messaging/guides/push-notifications-ios
I'm drawing blanks.
The AppDelegate functions to register for remote notifications is working well - the iOS devices successfully provides the device token to the Twilio Client. However, the TwilioIPMessagingClient gives no indication of success or failure while registering the token. Moreover, I don't get any sign of push notifications when messages get sent. I'm not sure how to debug this any further since Twilio is a black box for APNS pushes.
Is there a logging service inside IPM/another debugging method I can access to see the status of APN pushes?
