What this means for your store
- Because Ajax Cart AutoUpdate does not declare HPOS compatibility, WooCommerce flags it on WooCommerce → Settings → Advanced → Features. Test it on a staging copy with HPOS enabled before switching your live store, or ask the developer on the plugin's support forum.
- If your store uses the block-based Cart and Checkout (the default for new WooCommerce stores), check that Ajax Cart AutoUpdate's features appear there on a staging copy. The classic checkout (the [woocommerce_checkout] shortcode) is the fallback.
