I’ve tested my card url http://whisp.to/149169 with https://cards-dev.twitter.com/validator. Although it says “*.whisp.to whitelist request for player card was approved 11 months ago”, it doesn’t appear even in my tweets’ details page. It was working as intended at the very early days of the approval but it no longer does. I’ve reported the issue to developers a couple of months ago and they reported back stating that it’s sorted out. But the problem persists. My player card renders properly on card validator and log info says:
INFO: Page fetched successfully
INFO: 37 metatags were found
INFO: twitter:card = player tag found
WARN: Not whitelisted
So, may any developer help me to fix it please?
