How to re-register device token if it is updated or invalidated

[giangnt1]

Twilio recommend implementing the following logic to check if the device token is updated or invalidated

- Invoke [TwilioVoice registerWithAccessToken:deviceToken:completion] the first time the App is launched
- Store the device token and the current time. This is necessary to determine if the device token has changed
- Implement PKPushRegistryDelegate and check when the token is updated or invalidated. Compare it to the token value stored in 2. If it has changed, invoke[TwilioVoice registerWithAccessToken:deviceToken:completion] and store the new device token value.
- Check when [TwilioVoice registerWithAccessToken:deviceToken:completion] was last invoked. If it has been over 6 months, register the token again to not let it expire.

Example: https://github.com/twilio/voice-quickstart-ios/blob/master/ObjcVoiceQuickstart/ViewController.m#L209

How can I implement this with react-native-twilio-phone? Is there any method to check the device token is updated?

Hi,

This is managed on iOS by RNTwilioPhone here

When token is updated, react-native-voip-push-notification is sending 'register' event. RNTwilioPhone will then fetch a new access token and call the register method.

Same thing happens on Android here, but the event is sent by react-native-firebase/messaging

That means I don't need to do anything, RNTwilioPhone already managed the device token updated event, is that right? I just got an issue with register/unregister the device token, unable to make a call until I completely remove the application then re-install it and register the token again. I asked Twilio for help and they suggested implementing the token updated login above. Do you have any idea?

Ok are you able to reproduce this issue? Tell me the steps you did so I can reproduce.

Thanks.
