Trouble entering chords since last update(s)??

[nimbleswitch]

Is it just me? Lotsa times when entering chords and their qualities, I'll touch a button and the button label will flash up (so I KNOW I've touched it) and the button will stay dark, but it hasn't enter anything. When I'm done entering the chord, it's wrong and I've got a do over. Never had this difficulty before the most recent update(s). Thought it must be me and I'd get better at going slower, maybe, but I'm not, and that wouldn't account for the button going dark and not entering anything, anyway. Am I the only one who's noticed this? If so, just ignore this please.
