bump. Is Apple listening?

I'm having the same problem now for an "advanced" app clip experience I submitted a week ago. Older app clips with the same URL but a different query parameter are working fine. Does Apple really support app clips any more? They were first available with iOS 14 and the process is still buggy and frustrating. They should at least give some guidance on what "Received" means and how long to reasonably wait before it's working.
