What the “pantry items running low” card means

When pantry items are running low but aren’t on your main list, a card such as 3 pantry items running low appears at the top of your main list. Tap Review, tap the ones you need, then tap Add number to a List and pick a list.

The card only shows when you keep track of your pantry. The Running Low button at the top of the list shows items already on your list that are running low.
