'Opensea Import smart contract not working for Polygon Testnet Mumbai

I get the following error when trying to use the import smart contract https://testnets.opensea.io/get-listed/step-two

We couldn't find this contract. Please ensure that this is a valid ERC721 or ERC1155 contract deployed on Mumbai and that you have already minted items on the contract.

Everything is working fine with my smart contract I was able to mint and add it to my wallet.

Does anyone know what i'm doing wrong when importing to opensea?
