Expo Doctor Diagnostics

Run within xhr-latest (app presenting with issue) directory

✔ Check Expo config for common issues
✔ Check package.json for common issues
✔ Check native tooling versions
✔ Check dependencies for packages that should not be installed directly
✔ Check for common project setup issues
✔ Check npm/ yarn versions
✔ Check for issues with metro config
✔ Check Expo config (app.json/ app.config.js) schema
✔ Check that native modules do not use incompatible support packages
✔ Check for legacy global CLI installed locally
✔ Check that native modules use compatible support package versions for installed Expo SDK
✔ Check that packages match versions required by installed Expo SDK

Didn't find any issues with the project!

I'm seeing this as well in an Expo Development build.
