I am wondering if this is a bug with the trello app or something with my phone? On Samsung galaxy phone and when I go to "edit labels", any time I tap a label to add/remove it from the card the list scrolls all the way to the top. It's annoying because I have about a hundred gray (invisible) labels I'm applying to things so I can make automation to move certain categories around, so I have to spend most of my time scrolling when I want to add multiple labels to something.
Does not happen when I use trello on my laptop browser.
