Hi Tony, hi Rose,
I updated all the plugins and theme to latest version.
I disabled all the third party plugins, and nothing changed.
Then I checked your demo website, and the issue is present there, too, so I don’t think it’s related in any way to my installation / cache / plugins.

See this screenshot:
When you put a product in the cart the “spend XXX amount to get free shipping” is correct. As soon as you update the quantity IN THE MINI-CART (or off-canvas cart, in the image above), the XXX amount is not updated anymore and is wrong.
On my installation the pop-up cart subtotal is correct, in your demo website the off-canvas subtotal is also wrong / not updated correctly.
Thanks for your support.
