Hi there! I understand you're having trouble logging into the Hostelworld app on your Android 16 device; it redirects you to the browser, and after entering your login info, you see a "not found" message, and then the app crashes. Let's work through this together.

To start, could you tell me if this happens every time you try logging in, or was it just a one-time issue? Also, have you tried logging in through a different device or browser to see if the problem persists?

Meanwhile, here are some steps we can try to fix this issue:

1. Clear app cache and data:
- Go to your device's Settings > Apps > Hostelworld app.
- Tap on Storage, then Clear Cache, and Clear Data.
- Please note clearing data will log you out, so make sure you remember your login details.

2. Update the app:
Make sure your Hostelworld app is updated to the latest version in the Google Play Store. An outdated app can cause such issues.

3. Check default browser settings:
Since the app redirects you to the browser, ensure your default browser is working fine and up to date. Sometimes, link handling between the app and browser can fail if the browser app has problems.

4. Try logging in via the Hostelworld website:
Open your browser directly and go to the Hostelworld website to log in. This will confirm if your account and credentials are fine, or if the issue might be on the server side.

5. Reinstall the app:
Uninstall the Hostelworld app and then reinstall it fresh from the Google Play Store.

If after these steps, the redirection still shows "not found" and crashes, it could be a bug or server-related issue. In that case, I recommend sending a quick email to our mobile support team at [email protected] with details (your device model, OS version, app version, and error message). They can help investigate further.

Would you like me to walk you through any of these steps or check something else based on your experience with the problem?
