RevivSerums.com review for VNest ChatGPT Shopping Feed

Can't get any word from support despite multiple attempts through several channels. In "fixing" our non-existent robots.txt liquid file, the app prevents our Google Ads account and similar from crawling our site. Big non-no which prevented all ads from running. It also puts attribution data into our customer's Order Notes field, which is customer-facing in our email notifications and I suspect overwrites any note the customer puts there in our shopping cart.
