[push-notifications] Cannot send notifications using ExpoPushToken (Expo 40)

🐛 Bug Report

Summary of Issue

After upgrade to Expo 40 and iOS, I have a problem with sending Push Notifications using ExpoPushToken. The issue happens only on a standalone app, in Expo client everything works fine.

During the debug process, I had tried to use DevicePushToken and I managed to send and receive notifications (using node-apn with keys from expo fetch:ios:certs). The device token is 645f97af437250b8207c3e4ddaff9d9850350bc4391cf895cdb526f502a9716d.

When I call exp.host/getExpoPushToken with deviceToken above I receive token ExponentPushToken[pXoWnIHNZytciNSC7M0LtC]. The notifications sent by this ExpoPushToken do not appear on iOS device.

IMO, the standalone build and certificates are just fine, as I manage to receive notifications using node-apn. Most probably the issue is somewhere in exp.host/--/api/v2/push/send or in the method that “links” ExpoPushToken and DeviceToken.

Can you check if there were any changes on expo.api that can cause the following regression?

I’d appreciate any help here.

  1. Okay, I think I was able to reproduce the behavior -> you need to install a fresh SDK 40 iOS app, then uninstall it, then reinstall it again. The ExpoPushToken doesn’t change, and the push notifications aren’t sent.

  2. We will need to deploy the fix, I’ll update here once we do. It won’t require any changes or updates on your end
