Today's update is very difficult to read on my iPad Pro (11 inch, 3rd generation, running iOS 15.4.1).
The title text at the top of each card, and the card type text at the bottom of each card is very bold, to the extent that it looks blurry and is very hard to read (see pictures).
There's also a long-standing bug, that's become worse in this update: the only way to "right click" a card to enlarge it and see its details on the iPad is to long press on it. But that selects the image and text on the card, meaning there's a blue box over it, and the iOS user interface for copying text pops up and sometimes obscures the card text. This always happened, but now there are several blue boxes instead of one, and the iOS pop-up obscures the text more often. I gather there may be ways in CSS to stop elements being selectable, which might help this problem?
