When uninstalling LimeSpot Personalizer from the Shopify Admin Panel, Personalizer does not have the chance to do a final clean up before it is removed. There would be some LimeSpot Personalizer code that remains in the store even when it is uninstall.
If you are seeing our boxes after uninstalling, please visit this article.
The lingering code would have no effect on your store as it does not add anything to the storefront or affect page load speed. However, if you wish to clean up our code, please visit this article.
