The ticket has been showing "Investigation Complete" since before I added the updates. It's not showing as closed. Can I expect someone to look at it since I've added the requested info, or should I open a new ticket?

Uploaded the sysdiagnose to FB24535065 (captured right after reproducing the failing Messages App Clip invocation on a device without the full app installed). Thanks Albert.

Thanks Albert, I've added the AASA link to FB24535065: Source: https://hb.fitiv.com/.well-known/apple-app-site-association (HTTP 200, application/json) Apple CDN-cached: https://app-site-association.cdn-apple.com/a/v1/hb.fitiv.com (HTTP 200, application/json) — matches source, with correct applinks (23Z9HXPNYJ.com.eurekadesignsolutions.motiFIT, component /hb) and appclips (23Z9HXPNYJ.com.eurekadesignsolutions.motiFIT.Clip). The Advanced App Clip Experience URL is https://hb.fitiv.com/hb. Happy to provide a sysdiagnose or a screen recording of the failing Messages invocation if that helps.

Thanks. Ticket submitted as FB24535065

I'm having what seems to be the same issue, so posting here to follow

@DTS Engineer I got a reply to my feedback ticket. They told me to create a post on the Apple developer forums lol.
