Which package manager are you using? (Yarn is recommended)

Yarn

Summary

This folder structure, using the group syntax doesn't seem to support linking to the index initial route of the modal stack

UPDATE: verified issue still exists in expo-router@3.1.2

I think the issue is that the router can't distinguish between the root index and the (group) index.

I theory, it seems like this should be possible w/ unstable_settings.initialRouteName but this is not currently supported

Can also define (group)/index.tsx but this isn't always ideal.

@leggomuhgreggo Can you please create a new issue on the main repo https://github.com/expo/expo, as development has moved there.

When you do so, can you please update your reproduction repo to be a minimal example. Providing a repo with 6 different apps is not a good minimal reproduction
