NFT Crowd sale on Polygon?

[stpoa]

Hi Is it possible to do NFT crowdsale using Polygon?

I did a crowd sale using Rinkeby and testnets.opensea.com. After deploying the NFT contract and NFT contract factory I used the NFT contract factory address for the URL and it worked fine as described in docs:

testnets.opensea.io/address/rinkeby/{factoryAddress}/0

After deploying on polygon I tried to use and it doesn't work for some reason. I get 404.

opensea.io/address/matic/{factoryAddress}/0

For deployment on Polygon I used:

PROXY_REGISTRY_OPENSEA: "0x58807baD0B376efc12F5AD86aAc70E78ed67deaE"

Example https://opensea.io/assets/matic/0xceA562B88299188Ab31aCAedf5a9B255C5921627/0
