rinkeby solidity code https://rinkeby.etherscan.io/address/0x2301334d923434ff569ba4fd7fc19c35758086be#code

nfts were showing in version 3.3.0 erc721a but not on erc721a 4.1.0

Looks like it’s an issue with OpenSea’s Transfer event listener. Did some tests recently and seems like they are sometimes unable to detect the first token minted.

Try minting more tokens or transferring the first token after minting.

Don’t worry too much about it, there have been projects published on mainnet using version 4.1.0.

I had this same issue. Please see my solution here.

yeah - this is a supportsInterface issue; see the migration notes here on how to fix it: https://chiru-labs.github.io/ERC721A/#/migration?id=supportsinterface

Specifically, update your supportsInterface to be:

function supportsInterface(
    bytes4 interfaceId
) public view virtual override(ERC721A, ERC2981) returns (bool) {
    // Supports the following `interfaceId`s:
    // - IERC165: 0x01ffc9a7
    // - IERC721: 0x80ac58cd
    // - IERC721Metadata: 0x5b5e139f
    // - IERC2981: 0x2a55205a
    return 
        ERC721A.supportsInterface(interfaceId) || 
        ERC2981.supportsInterface(interfaceId);
}
