Karigaari India review for Google & YouTube

None of my 1000+ products are showing on Google Shopping Tab. And "Product Snippets" under Google Search Console shows only 4. Seems like this app is not generating rich snippets properly. It's been months but zero visibility on google while my same products are generating thousands of orders on Amazon. Things are complex to setup on merchant center, search console, analytics etc and still zero results. On top of it, Merchant Center's "Store Quality" shows incomplete shipping policy and return policy even though this app has synced it.
