My NFT won't show in MetaMask


I’ve recently launched my first edition, and I’ve noticed that the image of my NFT is not showing in MetaMask. Also, the name displayed is the symbol of the contract rather than the name of the NFT.

I’m also wondering, is there any way to set a thumbnail for the link to the claim page? When sharing on Twitter, the link doesn’t display any, although I’ve seen some other links to claim pages that have a thumbnail.

Thank you!
