I did the upgrade today on our 2016 and it went flawlessly. All the Flex specific functions are intact but with a much cleaner and nicer to use interface.
I used the tutorial linked below as a guide and used the Syn3 Updater program on the Cyanlabs website to create my USB drive for the install. Took about 30 minutes total to load everything, reboot and be ready to use.
Music playback off USB was no issue for me. Played WAV, FLAC & MP3 with no issue and as long as the metadata is tagged correctly (MP3Tag is a perfect program to fix issues like that) sorting via Artist, Album, etc. is no issue
