Edit the availability for all regions to be the same as your online store
In this article
The availability [availability] that you've listed in your product data for one or more of your products' regional overrides doesn't match the availability listed on the landing page for that product in those regions. This could be true for one or more products and one or more regions.
For example, let's say you sell honey and the availability for honey in a particular region is listed in your product data as in stock, but the availability for that region on the landing page is listed as out of stock. This results in a mismatch. If a product from even one region is mismatched, the whole product will be disapproved. As a result your offer has been taken down.
To resolve this issue, update the regional availability in your product data to match the availability listed on the landing page.
