Further to this, all other aspects of syncing between accounts seem to work, wallpaper, onedrive etc etc however the live tiles and start menu layout don't match. Its quite a pain to keep shuffling them around to match and adding and removing different apps/links.
Come to think of it I can't remember it working in 8.1. Has it worked for anyone else?
All my sync yes/no buttons are on to sync but it doesn't seem to make a difference.
