Multifeed Google Shopping Feed

As of today I have many issues with this app. There is only very slow email response, and too much back and forth clarifying my simple questions. The process of editing products and making changes is unreliable and complicated. Their recommendations (when they get around to responding) are not definitive. "It may work" "You can try this" etc. Need help today for my basic issues. Will change review if they can be resolved.
