To access these buttons, first, launch the Music Application on your iOS 10.2 device and play any song. When you will be on Now Playing screen, just swipe up and by doing so it will reveal the Shuffle and Repeat buttons.
If these buttons aren’t activated then they will have a gray background but if they are activated then they will have red background indicating that this button is on right now. Tapping on repeat button twice will repeat the track that you are listening to instead of the whole album.
So, were you able to access these buttons on your iOS 10.2 device? Let me know in comments below.
