Applinks for any subdomain not opening the app

My Entitlements file contains the following (removed some non related entries):

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>com.apple.developer.associated-domains</key>
	<array>
<string>webcredentials:app.mydomain.org</string>
<string>applinks:*.mydomain.org</string>
	</array>
</dict>
</plist>

Now when I tap on a link such as abc.mydomain.org, the app is not opened. If I change the generic applinks key from *.mydomain.org to a specific domain, this works correctly and it opens the app as expected. (This makes me think the website part of the AASA file is correct).

Since I need to support a lot of subdomains (think about hundreds in the near future), I really need the wildcard to work.

Do you have any tips on how to make this work?

Thanks for your post, you do not need an entitlement to use Universal Links. Can you explain where the entitlement came from?

In your previous entitlement snippet, you included <string>webcredentials:app.mydomain.org</string>

This specific entry is not required for Universal Links.

I'm looking forward to understand your project and what you are trying to accomplish.
