We have our apple-app-site-association file hosted on our website. It passes AASO verification, we can pull it successful as application/json via curl, and it also shows up as expected with a https://app-site-association.cdn-apple.com/a/v1/ourdomain.com link - however only in Europe.
The apple CDN link works in: Czech, Finland, UK, and Spain, however it does not work in U.S., Phillipines, or Canada. In those cases, the CDN page shows "not found".
It's quite strange that it only works in Europe. The file we are hosting doesn't have any IP restrictions that we are aware of, and we can access the file URL hosted on our website directly from the U.S. and Canada. So it seems that only Apple's CDN cache is failing to retrieve/store it for some reason, in certain locations.
Has anyone seen something like this?
