Not working with Grouped Products / Product Bundles

Bogo is setup to add a free product (grouped product) when spending X amount and using a coupon.

After adding X amount to the cart (using only a grouped product) and adding the coupon, the message for the coupon is displayed with 0 discount and the free product is not added to the cart (option to auto add is set correctly).

I’ve tested with YITH Woocommerce Product Bundles and Woocommerce Product Bundles. The later is indicated as capable of working with this plugin by the developer: https://www.pimwick.com/pw-faq/grouped-products/, however the bogo doesn’t work.

None of the 2 plugins mentioned above use the simple grouping mechanism that WooCommerce core uses.
