I just installed my new ATV4 today. Install went smoothly, and I could easily access my large iTunes music library on my iMac on the same network and play it through the ATV. Came back a couple hours later and now when I select "library" in the ATV4 Music app it says "You have no music on this Apple TV" Can't figure out how to access my music Library. The ATV4 continues to access other content on the iMac (Podcasts, Radio stations) without any issues. Any ideas?? Think I've stumbled on what I think is the answer. I updated the TVos between the two attempts to access the music library. It now seems to be located in "Computers" rather than in "Music". Is this correct?
