Boosters are not synchronised between my FB CCS and King's Microsoft CCS.

I've been playing CCS all these while via FB on my PC (Window 10). Recently I've installed the Microsoft King's app in my PC so as to play Level 2886-2900. I understand that everything will be automatically synchronised between the FB CCS account and the King's Microsoft account. However, it doesn't appear to be so cause with the exception of the goldbars, the rest of my accumulated boosters remains only on my FB game and are not reflected on the Microsoft game. I understand from some player friends that they doesnt have this problem at all. I have tried several times over the last few days, uninstalling the app and re-installing it again but to no avail. As such, I'm prompted to write to your goodself and would appreciate if you could advice me on this matter. Thank-you and would await your soonest response.
