Elderflower Botanicals review for Google & YouTube

It would work as expected if the developers had taken the time to give the user the choice on what variants to feed to google merchant or not. The app is feeding all the variants per product which I do not want. The most expensive variant shows at the top on google shopping and make my products look more expensive than the competitors'. The less expensive variants do not rank as high. I am expending money on a campaign and this app can not even give me the choice to pick what variants to advertise or not. I get many impressions in google but a few clicks and no purchases. This is lack of vision is costing me money. I may unistall this app un less they fix this ASAP. Seems like an obvious problem.
