I'm on macOS Catalina and I am using the standard macOS keyboard shortcuts to type Spanish accents. EG [option][e]-[o] to generate ó, [option][n]-[n] to generate ñ. When I type an answer into an exercise, the font color is white until the moment that I type any accented letter. At that point the font color changes to black and remains that way for the rest of that answer, but reverts to white on the next exercise. Is this normal behavior?
