Incompatibility with Variation Swatches Plugin / sticky footer

Hi,

we use the following plugin (https://de.wordpress.org/plugins/woo-variation-swatches/) to make the selection of variants more user friendly.

This plugin hat 300.000+ installations.

I added some screenshots to demonstrate the value of that plugin.

It also seems to integrate visually with the sticky footer cart but then, adding to the cart is not possible. It always complaints that no variant has been chosen.

This is a real pity, because it prohibits us from using the sticky footer cart.

It would be nice, if the sticky footer cart works with the widely used plugin.

Thanks
Stefan
