We recently transitioned to store our NFT metadata on the Arweave blockchain. Every time you create a NFT, the transaction is visible on etherscan while the metadata is stored on arweave. Thus, there are two transactions .
Click on your token as below. You can see the URL of the token.
The first number is the etherscan transaction. The second number is the arweave transaction.
Type in https://arweave.net/tx/ and add the last URL as marked above.
You can check with this URL if your NFT metadata has been uploaded.
If it looks like this ("Not Found"), your NFT metadata has not uploaded. We advise you to mint a new token and apologize for the inconvenience. We are experimenting with a new technology and things improve on a daily basis. We are working on a solution for this.
