Every time I try to add more than 10 copies of any one card (when I am on the card detail site), the site crashes (Opera/Win10). It is the same on the Android App. It is the same if I try to add more than 5 copies of one card in the grid with the right click option "Add card to collection".
Anyone else experiencing this?
Apparently I was not (I was using the browser version). Works for me now :) Thank you very much!
