Bug: In the new update (10.3.5), need to click "Keypad" before RingCentral phone allows keyboard input

When I am making phone calls. I usually press 0 for operator and things like that. Before the 10.3.5 update, I was able to just press keys on my keyboard to input as a touch tone phone. Now that doesn't work unless I click the "Keypad" button during the call.
