Hello all - we have enabled our app users to create and sign in using their passkey. However - for some users, we get a NSLocalizedFailure reason exception that the app is not associated with the domain.

We have ensured that the endpoint /.well-known/apple-app-site-association isnt blocking any requests.

Like I said before, 90% of our users are able to successfully create and sign in with their passkey but we receive the above error for the remaining 10%.

Any suggestions/guidance on how we can resolve this would be helpful and greatly appreciated. Thank you.

We learned there was an issue where the Associated Domains lookup could fail if it was attempted immediately after an app had been installed. This should be better starting in iOS beta 4. If you're having any more issues on beta 4 or later, please let us know through Feedback Assistant!

I am facing a similar issue while registering a PassKey, it is super rare, but we are able to reproduce it for 1 out of 100 new users

Could you share the error code that you receive, is it 1004 ?
