Player card validation


We submitted Photo and Summary Card with Large Image as well as a Player Card.

The Photo and Summary Card got validated instantly, but the Player Card validation hangs although the validator found no errors and the video embed does not have any mixed https content issues:

INFO: twitter:card = player tag found
WARN: Not whitelisted

How long does it take for being whitelisted?
