I'm having trouble toggling the "heart" icon on the Mac version of Apple Music. I can't seem to get songs I've "Loved" to become un-"Loved." I'm also noticing the "Loves" aren't syncing across devices, as when I go to try to do this on one of my iOS devices, the song appears un-Loved without me attempting to un-Love it.
iMac (27-inch, Late 2013), OS X Yosemite (10.10.4)
