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
