We’ve been running Player Cards for months now and today I received a random email stating that “the URL you provided for grabyo.com to use the player card did not validate. Please make sure the page contains valid metadata, then reapply for a Twitter card.”
No metadata has changed and putting the example url through the validator validates all the necessary meta tags.
It just seems like our whitelisted url (grabyo.com) has been removed by mistake? or revoked without warning?
The example of a url where Twitter Player Card should work on (and has been working previously) is: https://grabyo.com/g/v/Xwmj2MOeebV
Can someone please look into this asap please?
