Since the new builder release, the drag and drop function of builder is broken, it doesn't upload images, the browser just opens the images in the tab. It's across all broswers on Windows 10, but seems to be less so on Mac. I haven't had this issue with any other apps with the drag and drop upload (like Google Drive, MailChimp etc), everything else seems to work fine.

Has anyone else experienced this? I contacted litmus a month ago but they said it's at the bottom of the que since it's an "edge case issue".
