We have improved the user experience of the bulk upload process by removing any unnecessary text, adding a simple ‘clear uploaded files’ link, and emphasised the target area for the drag and drop upload mechanism. We have also made it simpler to resume a bulk upload if returning to it later.
(Note, if you have changed any of the user facing text on this upload page then this will not be removed by the upgrade. You can review this yourselves and delete if necessary.)
