Hello,

– About wishlist we are working to find what cause this issue. Please can you remove any third party plugin and test it again ?
– Removed the right sidebar
– By default wishlist isn’t designed for the mobile but we can add this on new update.
– Fixed also the responsive issue.
– To remove the breadcrumbs/sku/categories add this css in General > Custom Codes > Custom Css:

.woocommerce .woocommerce-breadcrumb {
   display: none;
}
.cl-product-info .product_meta {
   display: none;
}

– To add the registration form, you need to check “Allow customers to create an account on the ‘My account’ page” option in Woocommerce > Settings > Accounts&Privacy. The result: https://ibb.co/vH9LSWq

Let us know.

Regards!
