Cosmo is notorious. I don't think they ever post on their own. Or if they do, it's lonngg after the stay. I've heard it's because of their players club. Basically they have to manually enter the stays to make sure they're not being credited on both sides(double dipping). True or not, who knows? I just know that particular property, you better keep your receipt, as Marriott Associates do not have access to autograph collection properties' receipts/folios, and email it in, using the paperclip attachment method, not an in-line photo, as the firewall strips off most in-line photos, and don't bother calling unless you've already emailed in your receipt. Because the associate will not be able to post it.
