As per the apple documentation, I put:
<meta name="apple-itunes-app" content="app-id=MY_APP_ID">
in the HTML's head but the banner is not coming up in India where the app is available.
iPhone displays an empty, grey banner with a close button and nothing else. I'd expected it to show corresponding app banner.
I am unable to figure out what's issue. Any kind of help would be appreciated. Thanks
