Email autofill on Ghost.io isn't working (iOS and Mac desktop)

Thanks for the quick response Grey. I am not sure it’s helpful in this case, though, because as I understand it AD is about https://developer.apple.com/documentation/xcode/supporting-associated-domains. In my case, however, there IS no app. I’m using a website and attempting to get 1P to autofill using the site’s domain.

Why isn’t it simply using the site’s domain to run the search? This could easily be a Ghost.io problem in the end, but I feel I need to understand a little better what the problem actually is before I ask them to implement any sort of fix.
