Hello,

If you check on Ipad width you will see the same price as specified at the top: https://prnt.sc/1021qbs and https://prnt.sc/1021qn0

On the mobile, you can see button without the price: https://prnt.sc/1021rcg

When I add the product to the cart, it is added with the correct price.

The sticky add to cart does not show any price and amount it is not a bug, it is the view it has on mobile.

Best Regards
