I’m really sorry for any confusion or frustration, as that is not our intention. Previously, not all sellers were able to update their Max Order Quantity through Seller Central, so we provided the option to update it through the launchpad. However, all sellers are able to update their MOQ through Seller Central now. We are working towards removing the option in the launchpad. It's such an important step and we believe it should be done through Seller Central to ensure it is done correctly. You can set the Max Order Quantity in Seller Central using the following instructions:

Go to Inventory > Manage Inventory > Edit > Offer tab > Max Order Qty 1 > Save Changes

Let me know if you have any other questions!
