I have encountered a very serious bug in magento2.2.6. This bug removed almost all product data from my store. Detailed description link for this bug：https://github.com/magento/magento2/issues/15935 I am a database backup on June 14th. I tried to restore to this database and export all the product data, then import, but since I was migrating the product data from magento1.9, I have encountered a lot of import errors. So I gave up this method to restore my product. I want to restore my product by exporting the product data sheet for the June 14 database and then overwriting my current product data sheet. Can this fulfill my request? I am very anxious now, can someone help me?
