We are currently doing our beta testing for our application and we are having some issues with universal links. The issues can be seen below:

we are using auth0 for authentication. In this process, after users verify their email addresses they should be redirected back to the application. For some users, they are directed back to a page that shows error 404. For other users where it works, they are directed back to the application. What could be my issue?

Our app-site- association file is hosted in the link below for reference.

The file seems okay and has four paths.

I would recommend going over the Tech Note to debug common issues with universal links: https://developer.apple.com/documentation/technotes/tn3155-debugging-universal-links

Refer to the Tech Note for instructions on how to verify the file's format using the command 'sudo swcutil verify.' It is a comprehensive resource that will also guide you through setting up the file correctly. Please feel free to share your file here so I can provide further recommendations and suggestions.

Also, check your server settings where you host the file to ensure that it accepts all browser requests and traffic from user-agents of the form 'AASA-Bot/*'.

I hope this helps resolve the issue!
