Shopper and Stock Remaining Counter is loading slowly on the product page
Shopify loads Shopper and Stock Remaining Counter after the rest of the page finishes loading, and so it can take a while for it to load on pages with lots of images.
Unfortunately, there is no solution or workaround to this problem at this time.
We will be upgrading the app so that it installs in shop themes and loads instantly, but we do not yet have a timeline for this.
