OpenSea Buyer Can’t Purchase My NFTs—Need Immediate Assistance

A buyer is trying to purchase two of my NFTs on OpenSea, but they are unable to complete the transaction. I don’t know why this is happening, as everything on my end is set up correctly. My NFTs are listed under Polygon, meaning they should be free to transfer, yet this issue keeps occurring. This isn’t the first time—it has happened multiple times now. OpenSea, I need a clear explanation of what’s going wrong and how to fix it. If buyers can’t purchase NFTs, this directly affects my ability to sell. Please provide urgent support! Has anyone else faced this issue? If so, how did you resolve it? I expect a prompt response and a solution!
