Summary card works on web but not on ios app


I tried below link on card validator, it works well. I have one twitter including same link and i can see the summary card on web, but I cannot see it on ios app. Why? Note this site is SPA built with AngularJS. On server side we track the request with “user-agent” “Twitterbot” to display a static html page with necessary tags.


solved, my ios twitter is too old. after upgrade and it works. i forget what’s my old version.
