Please kindly note it here first that for expired or deleted status images existing on our APP end, we fail to optimize them directly as we have no data saving on the backstage and could not get the deleted images either at all. The only way to handle this kind of issue is to get merchant end authorization first if can let us delete merchant previous optimization records on our APP end first, so that we can let developers resync the current latest images on our APP and let merchant optimize them one more time under related settings. Also please claim one thing that by deleting the previous optimization record on our APP end will not harm or affect merchant Shopify store backstage images at all.
