App Card Not Directing to Google Play

[vearlo]

My app card validates, but it directs to my website, not Google Play.

<!-- Twitter App Card -->

Any ideas on what I’m doing wrong?

Thanks

It looks like the card will direct to Google Play only when posting the Google Play URL in the tweet, and the website when that URL is in the tweet. I guess my assumption was that any post from @Vearlo would generate the app card.
