Device tokens remain the same while users transfer app from previous iPhone

#1

Hi guys,

I’ve met an issue when users transfer their apps from previous iPhone to iPhone XS Max, push notification only works in the previous phone. And the reason is the device token generated from Expo.Notifications.getExpoPushTokenAsync() is the same in two devices.

How does device token work? Does it generate when users install the app?
Currently, reinstallation can avoid this problem, but the UX is not good.
Can we regenerate the token again even users don’t reinstall the app?

Thanks for the help :smiley:
