Why don't sold NFT pricing from the gallery to any marketplace show up?

I use Manifold gallery / claim page to do private sales. It saves me from any marketplace fees (thank you). When that collector buys, it shows the price on the claim page, but it never seems to show on OpenSea, SR, or any marketplace. Why is this? I would love to have that be more transparent so the collection has that history, but the only way is for users to click on the Etherscan, it always shows zero on the page.

ex: @alimo | SuperRare. I’ve had claim page on this collection, yet it shows no pricing on SR. Any ideas?

Hmm - This is good feedback. If there is a sale on SR, is the price reflected in Opensea?

From SR to Opensea this shows, but nothing from Manifold ever gets synced in

Ah ok i see - Do you have an example?

honestly I don’t, but if you guys poke around you can see. I think it’s odd no pricing is showing anywhere on any marketplace
