On all of my devices, my "Liked Songs" list is different. The list on my home desktop doesn't have any songs added after January 2nd. My office computer appears to have the most recent additions. My phone was missing a few in between.
I've tried updating my home computer and logging out/in. I can't get the list to update. Currently, I have ALL of them open (remoting into work) and my home list is STILL not updating.
