Why can I not edit my menu on the Grubhub merchant portal anymore?

I just connected Grubhub with OrderOut. I lost access to my menu on the merchant portal. Please help!

Your Grubhub menus is managed by the OrderOut integration. You will not be able to manage your menu through the Grubhub merchant portal, or a Grubhub tablet. Instead, the menu will be edited through the OrderOut menu editor found here.
