Ced Google Shopping Feed & Ads

The next day after installing this app, many of my products were not published on Google (now 48 and 7 before), I checked with their support team and they told me to contact Shopify directly without checking anything on my website, I believe they might have received many complaints like this. And I received messages through WhatsApp from this app's team and asked if I need any help as they see that many of my products are not published, however, after I said yes and no reply from them. What I can do now is remove this app and find a way to get my products published on Google. It's wasting my time, it didn't help my SEO but is harmful, and now I have to fix everything by myself, it is the worst experience ever!
