Once you have queued up a sync request you can check on the status of the request by going to Inventory > History > Sync Inventory History.
From here you can see the request in the queue. Once it is picked up it will move to in process and the complete when we have submitted the update. If there are any errors or updating your inventory balance or issues locating the product on your sales channel, you will see it in the message area on the support screen.
If you have any questions about a sync error message or are still receiving the error message, send a ticket to firstname.lastname@example.org with the error you received and the SKU so our team may take a closer look for you.
