Ebay feed from shopify not working

[Arkwright]

After months of working perfectly today our feeds from Shopify stopped. We are selling through shopify and ebay but not getting notification when a product has sold on Ebay so in turn is not syncing our stock, an absolute nightmare 

Cant re sync because the message: Sync job running in the background has been stuck for days! 

Help!!!

If you are using a default eBay app (https://apps.shopify.com/ebay), try opening the ticket with the app support directly.
