Unable to associate domain in non developer mode

Hi,

I have a problem with associated domains developing Passkeys app.

Adding alternate mode(developer mode) to Associated Domains Entitlement, it works fine.

But in non developer mode, CDN doesn't seem to read the AASA file.

• AASA file's path is: https://(host).(rootdomain)/.well-known/apple-app-site-associtation

• I checked the TLS certificate conditions and all conditions are met. https://support.apple.com/en-us/HT213464

  https://support.apple.com/en-us/HT210176

  https://support.apple.com/en-us/102028

Is there another reason why it only works in developer mode?

Thanks for your reply.
