Our team is going to be updating the links we use for deeplinking soon, and it’s very important to not break deeplinking in production. We are doing QA before release. But since iOS 14, when we start QA we have issues with deeplinking for around three days before it starts working.
Will Apple please provide us with some information about how often the CDN's cache is invalidated and what happens if the request for apple-app-site-association files fails? Without this information, we don’t know how the system works, if the issues we have in testing will impact production, and if our users will experience deeplinking not working. Deeplinking is a very important feature for our app, and our users’ experience should not suffer because Apple won’t share documentation with developers.
I see in
https://developer.apple.com/forums/thread/658454 that the user-agent string for the Apple App Site Association CDN bot is AASA-Bot/1.0.0, but there is still a lot of missing information about how the Apple App Site Association CDN works.
Could we add the “Universal Links” tag to this post (and maybe remove the “Linker” tag if necessary)?
Thank you!
