I have a shop archive page. In Woocommerce the site is set to go to the cart / basket after adding the product. In the archive there is an add to cart button that triggers the add to cart and then redirects to cart / basket.
There is an ajax icon that loads and uses the colours set up in the cart theme options.
The issue is that if you press back from the cart then the ajax icon is still loaded in the page and you need to do a page refresh to remove it.
I would recommend you hide this before doing the redirect so we don’t have this issue.
