Im having very similar issues on my end with associating app clips to locations in Apple Maps. Here is my app clip advanced experience setup along with my AASA file setup for the related app. Everything looks to be in order but there is there a way to check or verify if Apple sees/approves the association.

Typo in the original post: "When asking for clarification with the first criteria they said they could not help and closed the chat." We are are currently updating our AASA file to the latest format and I will make a post update if that works. Any additional help, guidance, or documentation would be appreciated, thank you.
