UPDATE:
The "dropping" issue may actually be with the keyboard itself and not the app.
I was using a wireless Apple keyboard from 2012 because the raised keys are closer to the feel of a typewriter.
However, when I disconnected that keyboard and connected the 2019 Magic Numerical Apple Keyboard there are no issues whatsoever. Works like it should. (Although I am not all crazy about the "feel" of the latest keyboard. Too much like a laptop. Bummers.)
