my products suddenly stopped showing by google ads, mailed, called, they there is no account issues but still my problem is not solved

For a free app/sales channel integration this can get you excellent results with both free Google shopping listings as well as smart shopping campaigns. We were seeing 15-20x ROAS on our smart shopping campaign from about the 4th month after installation, continuing for about 18 months. Although those levels are not what they use to be now, they are still decent. It’s important that you have a Google ads account and merchant center account set up and that your online store meets all of Google’s policies before connecting to your Google account. Once you connect your store to Google they will inspect your site and product listings and if your site does not meet all of the requirements then Google will suspend and possibly ban your account and it can be very difficult to get it resolved to try again. The app itself is a bit buggy and clunky. One major issue is that, even if you have product UPC/GTIN code entered in your product setup pages in your admin, Google will show your products as having no GTIN. While this doesn’t completely prevent your products from appearing on Google shopping listings & ads, it will suppress them from many search results and cause them to rank much lower. To fix this, you must go into the Google channel app and go to your products and change the ‘custom product’ field to ‘false’ for each individual product (it is blank by default). If you have a lot of SKUs this can be extremely time consuming, as you can only bulk edit fifty at a time, and each time you save, it starts you back over at the beginning of your list of products. There is no option (like in the products admin) to sort, filter, or bulk select more than one page of products. If you have 3000+ products like we do, expect to have to search, page by page for individual newly added products, only to be able to ‘fix’ one product and then start completely over from the beginning again to find and fix the next. These issues are the only reason for not giving a 4 or 5 star review.

I won't recommend using this! Since it is not working properly! The google shopping campaign must be done via google ads directly! This app is useless just like the support team of google ads.
