When trying to change the due date in ILLiad using the built-in calendar, moving through the months using the arrows results in an animation, and you can’t scroll to the next month until the animation stops for the current month. It’s just a fraction of a second, but when we receive a generous renewal of several months, it’s an annoyance to have to wait for the animation before moving to the next month, rather than having the month load instantly as it does in many built-in calendars in other software/apps. (Workaround: I'll try to get in the habit of typing the due date manually, rather than clicking on the calendar, since that's the fastest method of all.)
