A. 1. Check app settings: Go to the app settings and ensure that the default action for adding items is set to 'Add to Cart' instead of 'Add to List'. 2. Manually move items: If items are added to the list, you can manually move them to the cart by selecting the item in your list and choosing the option to add it to the cart.

B. 3. Restart the app: Sometimes, simply closing and reopening the app can resolve temporary glitches.
