Push Notifications don't work in TestFlight "Device Not Registered"


I just created a standard Expo project (not detached nor with create-react-native-app) for testing Push notfications using the latest expo version.

In development mode everything works fine: The device receives an ExpoPushToken and i can send notifications using it via the Expo notification tool.

When I build the IPA () and send it to TestFlight via Application Loader (latest version of Xcode) I also do receive a Token from the Expo API, but I can’t send notifications. I get the Error “Device Not Registered”.

Any ideas? Thank you!


Hey @cheesyeyes,

This behavior seems odd. Can you let me know what SDK version you are running?
