Cannot Select Online Grocery Order/Pick Up

When I open the Wal-Mart app, it takes me direc to the Walmart.com side of the app. When I try to select Grocery Order/Pick Up just to begin a grocery list, it will not let me select it. I'm assuming due to the holiday? I have not been able to use the Grocery Order/Pick Up option for several days though. I have the most current version of the app, and everything else seems to be working. From what I'm seeing here, looks like I'm not the only one.
