Achievements are not unlocking. (IOS MCPE) 0.15.6

Hi I have quite a few of the Achiements unlocked whilst playing now realms (survival). The second to last update (0.15.5) made it so they no longer unlocked. I was hoping the latest .6 update would fix the problem but it has not. I'm still playing survival MCPE IOS on realms nothing has changed.
