Issue with Extra Product Options at Cart & Caching

Hi there,

When we use extra product options and select to add an option with a price difference e.g +£10 when we get to the cart the product ‘price’ will show as the correct price, then after a few seconds multi-currency will replace ‘cache helper’ class with the original price, which doesn’t include the add-on in the price, but the line-total is correct.

If we disable the caching option within multi-currency this will work, however, of course, then breaks caching throughout the rest of the website.

As the cart is always an ‘un-cached page’ is there a way we can just disable this on a page-by-page basis? Or at the very least on the cart page itself.

We have tried using Storefront and also get the same bug, so, it doesn’t seem to be theme related.

I have copied screenshots showing the class that is replacing the currency and a video of what happens.
