The app changes left swipe function from Remove to Hide – this has been done to easily support decluttering your list when you’re in a store.
Left swipe on the shoppinglist is labelled Remove and can be invoked when a store is not selected. The action deletes the item forever.
Left swipe on the shoppinglist is labelled Hide and can only be invoked do when you are in a (selected) store. The item is hidden during your stay in the store and reappears when you are in a new place, so you can buy it there.
Hide item followed by minimization / reopening app means the items reappear. This is because one must have bought at least one item at a location before “hiding feature” kicks in.
