When clicking on a link in received email, it should navigate to my application but it is opening in safari browser. I have mentioned "*.test.com" as applinks in Associated domains under Capabilities in Xcode and in our web side we have deployed "apple-app-site-association" file in root folder. My server host name like "abc.test.com" and I have mentioned applinks like "*.test.com" this universal links with wildcard feature is not working.I have Enabled ‘Associated Domains’ in my app identifier on developers.apple.com, If I have mentioned applinks like "abc.test.com" then it is working fine. My application Developement target is 9.3.
