We have recently implemented the twitter summary card for our store page and also got approved but image is not showing on android during test.
When store page link is shared we are expecting that corresponding merchant icon should appear on card so followers will get good idea of what deal we are talking about. Summary card displays fine but instead of logo image, it shows gray image of camera with cross.
Image is 120x120 PNG according to twitter card summary type guidelines.
For example: tweet with link http://www.taazacoupons.in/coupons/amazonindia should show logo image of Amazon.
We have checked it on website twitter stream and found out that for some it shows correct logo but for some it shows cut profile picture instead of logo.
In Android it doesn’t display anything at all.
