Props.exp.notification is not set

Expo SDK
1

Hi Team, I’ve spent a day trying to debug this situation and I’ve read every single issue on Github related to this with no luck. I’m hoping someone can help!

So I have a simple Push Notification app with just the example code from [https://docs.expo.io/versions/latest/guides/push-notifications]

The issue is that my main App this.props.exp.notification is non-existent when I send a push to a standalone version of the app and tap on the notification. The app is standalone using exp build:ios and TestFlight test using SDK v26.

See post for additional details:
