 Music - hearts not syncing

[zamoht]

So, I spent the day yesterday "hearting" a big bunch of songs in iTunes. Today, none of those songs have a heart on my iPhone.

Is this an issue for more people than me?

iTunes 12.3 was supposed to resolve this, no? "Addresses an issue where songs you loved on iOS did not appear loved in iTunes"

...ah no, that's the other way round, silly me...
