Hi,
This issue is happening during Passkey creation.
We’ve observed that approximately 1% of our customer users encounter a persistent error during Passkey creation. For the vast majority, the process works as expected.
We believe our apple-app-site-association file is correctly configured, served directly from the RP ID over HTTPS without redirects, and is up-to-date. This setup appears to work for most users, and it seems the Apple CDN cache reflects the latest version of the file.
To help us diagnose and address the issue for the affected users, we would appreciate guidance on the following:
-
What tools or steps does Apple recommend to identify the root cause of this issue?
-
Are there any known recovery steps we can suggest to users to resolve this on affected devices?
-
Is there a way to force a refresh of the on-device cache for the apple-app-site-association file?
Thank you in advance for any input or guidance.
