the subject says it all: my twitter card (summary card, approved yesterday) shows the image when viewed in the Twitter for Android App but not in the Twitter website.
This misbehaviour may be found when visiting this tweet:
The URL in the card is: http://www.versvs.net/peatones-no-escaparan-controles-antidroga-trafico/
As the image actually shows up in the Android app, I think it is a bug with the web app. But maybe i forgot to configure something.
Any ideas? Thanks.
