Hey Kazuaki, I built this free tool to help developers test their AASA file more easily. It was actually recently featured by iOS Dev Weekly. Here's an example: https://getuniversal.link/yelp.com You just enter your domain name on the site and it'll grab the AASA file from your domain and Apple's CDN so you can compare behavior across both. Plus, it gives you an easy dashboard for creating test links and verifying behavior. Hope this helps!

It's not a complete solution to your problem, but it should help move things in the right direction: https://getuniversal.link/ I saw this website featured recently in iOS Dev Weekly that helps you test your AASA file. You just provide it your domain name and it'll grab the AASA file from their and Apple's CDN so you can test an update or the current version of the file indexed by Apple. For example, https://getuniversal.link/yelp.com gives you dashboard for testing all of Facebook's universal links.

I'm having a similar issue. Were you able to figure out a solution?
