My ads account were going very well until when I decided to upload my products in the google channel shopping and facebook channel. Few of them were wrongly marked by AI as violating policies (cheese violating healthcare policy, a nonsense) resulting in a suspension of my account. I have asked of course a review but God knows when I will be able to have back my ads account.
So for my experience, advertise your business, but don't upload your products on the FB or google Channels.
I recommend you have a look at my checklist to ensure you have not forgotten something: https://community.shopify.com/c/Ecommerce-Marketing/Checklist-Suspended-Google-Merchant-Center-Accou...
