NFTs are displayed under the NFT tab. Take note that some NFTs will not show up on the mobile app, or may not show up correctly. This is a function of MetaMask rather than Novel. To import your newly minted NFT, all you'll need is to be on the Polygon/Matic network, the Contract Address, and the Token ID of your NFT. Steps to find this information below.
Change your network to Polygon. Most wallets are defaulted to Ethereum. To switch networks, tap Ethereum Main Network under Wallet at the top of your Metamask screen. Next, click Add a network. Then, select Polygon Mainnet.
Find the NFT's contract address. While there are multiple places to find the contract address to your NFT, the easiest is through Polygon Scan. From your Novel Gallery, click on your NFT - then click View on PolygonScan.
At the top of the page, you will see an Overview and Profile Summary section. Within each section, you'll find your Contract Address and Token ID.
If you're doing this from a computer and need to get your Contract address and TokenID - feel free to send yourself an email with those details or if on a Mac, copy and paste.
In the MetaMask Mobile app, toggle to the NFT tab. Scroll down and select Import NFT.
Paste the Contract Address in the first text field.
Next, find the NFT's ID, also referred as the Token ID. The Token ID is the unique identifier of your NFT on the blockchain. You'll find this under the Overview on the PolygonScan website. Make a note of it, or copy it.
Paste the ID into the field marked ID in Metamask Mobile.
Next, click Import and your NFT should now appear under the NFTs tab.
