We have two friends in Australia who we want to get into Kingdom 86 with us. However when both of the, made accounts they were put into kingdom 19. Both are still under 7, but Kingdom 86 does not show for them, only lower #'d kingdoms. So we made accounts for them in 86 and tried to link their devices to them, but they get a message saying the linking code has expired even though it has not. Any ideas?
