I'm attempting to construct an Uber link that will direct user from mobile web app to Uber (app or mobile website) with prepopulated drop off and pick up data.
Following this uber instructions for mobile web "deep linking", I got this link (appended to <a> element):
<a class="uber_butt" href="https://m.uber.com/sign-up?client_id=44oPVzp.....knAb_-0fI75&pickup_latitude=37.5&pickup_longitude=-122&pickup_nickname=My+location&dropoff_latitude=37.366209&dropoff_longitude=-121.976619&dropoff_nickname=Sibca+Square">
<div class="icon uber_icon"></div>
</a>
Now when I tap on this element from iphone's safari or chrome it redirects me instantly to Uber in appstore or to uber.com and then to appstore. Uber app is installed. So what am I doing wrong?
