WooCommerce Slow Add to Cart

Hello Everyone,

I have a wordpress site using Woocommerce, and I’ve noticed the Add to Cart button take a very long time to load after it’s been clicked, around 15 seconds. I’ve done a lot of searching and have been unable to find anything someone else has done that has worked. So far I’ve installing Heartbeat Control and WC Speed Drain Repair which didn’t affect anything. I also tried to remove the Shipping Calculation from the cart page because I heard that could slow it down and that did not affect anything. Lastly, I tried disable AJAX add to cart buttons on archives and this did nothing as well. Any suggestions or help is welcome. The site link is kyndclothing.com.

Thank you in advance!
Eric
