When you try to mint your NFT, you may get the following error - **Unknown Processing Time**. It’s usually because the **gas fee limit** is set up too low. To solve this issue, you need to first click on **Edit**.

Then it will bring you to this page, click on **Edit suggested gas fee**.

Try a higher gas fee for both the **Max priority fee** and the **Max fee**, like 40 or something, and click on **Save**. And it should be resolved as follows:

Note that the gas fee is fluctuating, so you may need to change it once in a while when the error shows up again.
