they work for my game pages (the cover images show ok), but not for my profile page.
from the twitter card validator:
INFO: Page fetched successfully
INFO: 11 metatags were found
INFO: twitter:card = summary_large_image tag found
INFO: Card loaded successfully
no picture shown. checking the source, there's a "twitter:twitter:image" tag with valid content.
I've randomly checked other people's profile. some work, showing the first listed game's cover picture, some don't, just like mine.
what am I missing?
(edit) found the culprit: there's a duplicate"twitter:" in the tag...
