The copies of your listing stored on Splitly is simply a cached version of your listing and may not always be up to date.
If you happen to notice any discrepancies with your listing on Amazon, or if you've changed it recently, or if some of your child ASINs not showing up, 99% of the time, this can be resolved by updating your product feed.
You can update your product feed under the Products tab. There will be a button called Sync Product Feed.
Once you click Sync Product Feed, the button will turn grey to signify that the feed is currently syncing. Once it turns green again, you'll know that the product feed has synced and we've pulled the new product data from Amazon to Splitly.
