sync products not working

When trying to sync my products following updates to the latest version of the plugin, we do not seem to be able to get all our products to sync via the import list screen.

Instead we are getting a page that is reloading each product instead of the old setup and once one product is no longer available it stops with an error:
Sorry, this item’s currently unavailable in your location.
and the scan stops, this makes it hard to establish which product this error is relating to and also create manuall steps to now investigate and remove the product.
