I'm having some trouble with the pump mechanism and could use your help. I've attempted to twist the spout both clockwise and counter-clockwise, but it still won't pop up as expected. Could you provide some guidance on how to properly deploy the pump? Any tips or instructions you have would be greatly appreciated, as I'm eager to get this product working correctly. Thanks in advance for your assistance!
