Hello,
1/ As you can see, it is not 8theme (our) widget, it is the default WooCommerce widget, so contact support of WooCommerce or your cache plugin.
2/ Try to add the next code in Theme Options > Theme Custom CSS:
@media only screen and (max-width: 768px) {
.etheme-sticky-cart .et-single-buy-now.single_add_to_cart_button.button, .etheme-sticky-cart .stock, .etheme-sticky-cart p.price {
display: none;
}
}
3/ What problem do you see there? Could you record a video? We’ve cheked the Wishlist functionality and it seems to work fine.
Try to: Theme Options > Speed Optimization > Always Load Wc-Cart-Fragments > On
Regards
