Hi all,

So in ERC721.sol, Openzeppelin has replaced '_isApprovedOrOwner' with '_isAuthorized'

therefore, in function flipMode to check the owner u must use '_checkAuthorized' instead of '_isApprovedOrOwner'

The new code for function flipMode should read as,

    function flipMood(uint256 tokenId) public {
        // Fetch the owner of the token
        address owner = ownerOf(tokenId);
        // Only want the owner of NFT to change the mood.
        _checkAuthorized(owner, msg.sender, tokenId);

        if (s_tokenIdToMood[tokenId] == Mood.HAPPY) {
            s_tokenIdToMood[tokenId] = Mood.SAD;
        } else {
            s_tokenIdToMood[tokenId] = Mood.HAPPY;
        }
    }

check the CHANGELOG.md at

line 203

Thank you,
