Cart gets empty with a page refresh

[Kuubs]

Hello

I have a strange bug, I just updated to the latest version 3.8.6. When I refresh my cart page, it says the cart is empty. But when I check my cookies I think the products are still there:

Name: Product91 value: 1
Name: Product81 value: 1
Name: Product87 value: 1

Are these cookies representing my cart?

And if so why is my cart empty when it is in fact full?

Ok so I checked and it seem to only happen on mobile.

Maybe you have a template with a template override that has JS errors
