This has been suggested in at least a dozen posts (3 or 4 by myself). I keep receiving answers that their is such a provision, I sure haven't seen it.
Another thing that might help, especially for us "older" people, especially us with limited vision is put the invite and timer on the bottom of the screen. Your eyes are focused on the bottom of the screen with the ding line, so your not concentrating on the top of the screen.
You may laugh, but wait till your old, only one eye , poor vision in the other, and than see how hard your laughing.
