If you have multiple NFT’s in your account, you will need to click on each NFT to load the specific account and then follow the withdrawal process.
If you have multiple NFTs that you are withdrawing from each NFT on the same day, your total amount of withdrawals will be calculated and you will pay the fee on the total amount of withdrawals, not a fee on each and every NFT withdrawal.
This will only be applied if the withdrawals of the multiple NFT/s are completed at the same time.
