didnt work with dynamic price

Hello,

I check your website. Basically plugin is to adding product to cart with ajax. It has no limitation or validation stuff in it.

Now the error you have asked is mostly you added in notice area which fire when page load. So if you use ajax, practically page is not loading again. So your notice will not appear too.

If you want to show it, you can change view cart text which coming after product added successfully on cart. You can google for same, filter for changing view cart text in woocommerce and will get that.

For Showing notice which you asked on top of page, that is directly not possible with plugin as page is not loading again like normal one. But if you have good knowledge of Js, you can prepend html to particular div and fire it after product added to cart. Little bit customize jQuery.
