> Apps may use in-app purchase to sell and sell services related to non-fungible tokens (NFTs), such as minting, listing, and transferring. Apps may allow users to view their own NFTs, provided that NFT ownership does not unlock features or functionality within the app. Apps may allow users to browse NFT collections owned by others, provided that the apps may not include buttons, external links, or other calls to action that direct customers to purchasing mechanisms other than in-app purchase. This seems like it restricts a lot of the imagined use cases folks had. You can't use them to unlock functionality.
