Hi, I'm a Trello returnee, having been away but occasionally looking back to keep an eye on when developments would let me return. Notifications in checklists did it, at last!
I'm fairly sure when I last looked at Dashcards in September '22, I could export a CSV of the data in dashcards. I was expecting to be able to do that because the button is still there, but it does nothing now.
Does it just do that in the Premium and not Standard tier now? There's no pop-up box saying so, (there are other limitations that I expected because they do say so) and it's not mentioned at all in the Help article on Dashcards.
