Note that if you have the Groove flight issue that does not allow you to play DRM content, try going into All settings>System>Apps Features>Groove Music>Advanced options>Click app Reset. This solved the problem for me. I had posted the problem in Feedback and someone gave me the answer that corrected the problem on 14332.

I have the same problem on the mobile build but mobile has no Advanced options to reset Groove. If anyone finds a solution for mobile, please post.
