[rubenwardy]

Minimal reproducible example

Summary

Expected behaviour:

• I build my app using npx expo run:android
• When run:android opens the app or I tap the app on the pixel launcher
• I see the index page

Actual behaviour

• When I open the app, I see "Unmatched Route - page could not be found"
• Clicking "go back" correctly goes to the index page

The app index is correctly shown when using Expo Go

This still happens if I move the app folder from src/app to app.

Possibly related to #28515 and #28367

[rubenwardy]

Possibly related (this doesn't have a fix though): expo/router#457

[rubenwardy]

As a workaround, I've created a src/app/com.rubenwardy.expo_rater_mre:.jsx file. But I shouldn't need to do this (or at least this should be better documented in the guide)

import { Redirect } from "expo-router";

export default function RedirectToHome() {
	return (<Redirect href="/" />);
}

I am facing the same issue, with the project where I get the QR code from the GitHub action for a PR, I will try to reproduce the bug in a public repo to display the error

@raajnadar This is fixed in 3.5.0, which is available as part of the SDK51 beta

[marklawlor]

@rubenwardy Can you please provide more description about your issue

I run the app

Can you provide more information about where you are running the app from? It appears you are opening a deeplink, how was this link generated (or which QR code are you using)

I can confirm this bug is solved in Expo SDK 51 & expo router 3.5.0+

It happens both with run:android opening the app and when I tap the app icon on the pixel launcher. I'm not using deep links at all
