Twitter Cards with Redirect URL not working

[iECONOMICS]

Our App have been approved and worked fine on first day, but it doesn’t anymore.

Here is the URL i am trying to share: http://ieconomics.com/exp/cc7e603dfe644090a76427f153430294
which redirects to:

http://ieconomics.com/explore/?s=china:unemployment%20rate,euro%20area:unemployment%20rate,united%20kingdom:unemployment%20rate,united%20states:unemployment%20rate&c=rgba(32,150,49,0.8);rgba(247,152,57,0.8);rgba(153,0,51,0.8);rgba(70,130,180,0.8)&t=spline,spline,spline,spline

Full Url works fine on card validator but the shorten doesn’t.

Also, when i shared the shorten url before it worked. Example:
https://twitter.com/iEconomics/status/485114020098093057

Any idea of whats happening?

Thanks

Might have been a cache delay. Looks like it works now.

Let us know if you have other issues!
