Any update on this? Same url working on iOS 18 and below when opening from default browser. But not working on version above iOS 18 ?

Thank you for your response. I double-checked the JSON, and everything seems to be in order. The only concern is that deep links using a redirection URL are not working, whereas direct universal links work as expected. This is the main issue. Also, could you please confirm whether switching to the new AASA format is mandatory for universal links to function correctly?

I see you have added double slash in the url v1//dl.punchh.com: When I try curl -v https://app-site-association.cdn-apple.com/a/v1/dl.punchh.com I get proper response HTTP/1.1 200 OK: Request completely sent off < HTTP/1.1 200 OK < Apple-From: https://dl.punchh.com/.well-known/apple-app-site-association < Apple-Origin-Format: json < Content-Type: application/json or may be when you have tried we were deploying something. Can you check again and confirm?

Yes correct with same configuration working on iOS 17 but not on iOS 18 and above. Here is the link to AASA file: https://dl.punchh.com/apple-app-site-association Configuration set on xcode: applinks:dl.punchh.com applinks:dl.punchh.io
