I sometimes have an issue with drag'n'drop function, when adding files to a card. This happens more and more often.
It could also be nice to be able to drag'n'drop files from project place to local desktop.
Thanks for your feedback. To me this sound like something you would need to talk to support about and see if there is anything they can do to help you with or they need to report this as a defect. I would suggest that you contact firstname.lastname@example.org and they will be able to help you within 24 hours.
