I have a Logitech K750 keyboard, which works 100% on an old 2011 MBP running Sierra, but for some reason, the media controls don't work on a new 2016 MBP with Touch Bar. Oddly enough, the rest of the keys on the function keys row work (brightness, volume, etc.). I've confirmed that my Logitech Control Center is up-to-date. Is this a known issue or something specific with my setup? Is there anything I can try? I've tried re-pairing the keyboard. Thanks in advance!
