Hi,
I shared my website from my iOS app as App cards and its not deep linking with the application,
The meta tag that I have provided in the website are given below
<!--<meta name = "twitter:card " content = "app"/>
<meta name = "twitter:description" content = "Description" />
<meta name = "twitter:text:title" content = "Appname" />
<meta name = "twitter:app:name:iphone" content = " Appname"/ >
<meta name = "twitter:app:id:iphone" content = "956511007"/>
<meta name = "twitter:app:url:iphone" content = "rmphone://podcast?id=1001"/ >
<meta name = "twitter:app:name:ipad" content = " Appname"/ >
<meta name = "twitter:app:id:ipad" content = "956511007" />
<meta name = "twitter:app:url:ipad" content = "rmphone://podcast?id?1001"/ >-->
If I open the page in safari, it works using iOS Universal linking feature.
