mini sidecar cache issues with ajax

Hello!

I'm currently using Flying Press cache + WP Super Cache.

And the performance results are incredible.

However, the mini cart cache is all messed up.

Reading here on the forum, I followed an instruction to disable this:

After doing this, it seems that the cart confusion resolved, as products appeared and disappeared, very strange.

But I still have the following problem now:

What happens?

If I add a product through the home or store, the product is "added" to the side cart.

But when I access the CART PAGE, no products are listed.

Now, if I open the PRODUCT page, and add it, when accessing the cart page, it is there, everything is fine.

The same thing happens if I try to delete the product from the mini cart. If you are at home or shop, open the side cart and delete a product, it seems to delete it, but it doesn't delete it….

When you access the cart page, the product is still there.

Now, if I go to the cart page and delete it there, it works.

In short: I need it to be possible to add or remove products from any page to the mini side cart in ajax and for this to work.

Can you help me?
