Ad pop-ups that interrupt EVERYTHING!
Youre thinking, calculating, crunching numbers, trying to be accurate with budgeting, bills, or ANYTHING, and get interrupted literally 2-3 times EVERY MINUTE with ads that pop up, block your work, interrupt your thoughts, and distract you with completely unrelated content. Used this app for over a year, and just couldnt take it anymore.
