@caseychoiniere Thanks, I updated my CRNA CLI to v2 and everything is working.

Same issue here. It took me several days to figure out what the issues were. Make sure you’re using create-react-native-app @ v2. I got the UnhandledPromiseRejectionWarning: when trying to use anything below the new v2. Then follow the steps I’ve outlined in the issue linked below to fix all of the other bugs/issues that were introduced when they merged create-react-native-app with Expo a few days ago. Mopst of these other issues are relevant only if you eject the app.
