There is an obvious and consistent bug in Reader DC. When you enter the page X that you want to go to in the X/Y display in the ribbon, you have to do it TWICE. (The first time it self-destructs.) Admittedly this is a minor annoyance, but it makes Adobe look a bit silly and unprofessional. The second bug ... when I check that I have the latest version of Reader, the whole shebbang crashes! (No way would I buy a paid-for copy of this!)
