Hi @naszam,

What weren’t you able to do with extending ERC721PresetMinterPauserAutoId that meant you needed to inherit from ERC721 instead?

I have created a new topic for: [What are the benefits of ERC721Holder.sol?](https://forum.openzeppelin.com/t/what-are-the-benefits-of-erc721holder-sol/2792) as I think it is best for the future community when looking for an answer to have a question per topic.
