Shift Cal - CuadraTurnos Lite

Very useful. Easy to use. BUT since I updated, it has this very annoying feature. It pops up with commercials that are loud. I realized this when I made the update and I was trying to put something in my work calendar and I was seating in a meeting and the loud inappropriate commercial played. I had it on vibrate, but the volume does not follow vibrate mode. And ads pop up more often now. I want to go back to the old version. I understand to make money they need ads. But they really need to have either no sound or have them pop up muted and give the person the option of un-muting if they want to listen to the commercial.
