iOS doesn't find certain routes (for instance '_sitemap')

[jmatsushita]

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

yarn

Summary

Some routes aren't found on iOS while they work on web and android.

For instance _sitemap doesn't work (either with a <Link> or a router.push().

Links also seem to not load on iOS when using shared routes.

Minimal reproducible example

Tested with [email protected] and [email protected]

For instance, /message works:

app/
  _layout.js 
  (home)
    _layout.js
    home.js
    message.js

but on iOS this doesn't (but works on web and android)

app/
  _layout.js 
  (home)
    _layout.js
    home.js
  message
    index.js

and neither does this

app/
  _layout.js 
  (home)
    _layout.js
    home.js
  (message)
    message.js

Provide a repro, it's unclear what's inside the layout files, where the navigation event is firing from, etc.
