Is currently working on a new M2 2.3 site to replace my M1. Almost done but I have found an issue with the cart and full page cache.
When full page cache is enable and I add a product to cart its all good. But when I move to another category and add another product the cart gets empty and start all over again.
If I disable the full page cache the cart works fine.
Anyone have an idea of what i might be?
The site is still in devolopment.
