You are a multibillion-dollar company and you want us to trust you to fly 30,000 ft above the earth's surface and you can't even manage to get the bugs out of your app. Fix the birthday calendar!!! I had to scroll back 50 years with the arrow button because it wouldn't allow me to change the month, day or year unless it was in the month of October 2026. FRUSTRATED !!!
