Armed Spoilers issue

Hi dears captains,Again a topic on this arming spoilers problem.I've read carefully another posts on the subject.With the 600/700, all worked properly.Now with the new 800/900, despite I know it had been worked out,it doesnt work properly:when on 'armed'position, (the green light on the main panel illuminates), which is done on the throttle panel, the spoilerdo not deploy at touch down, EVEN WITH THE YOKE AT IDLE position,well calibrated.I tried everything, it doesnt work.One always have to deploy them manually, which is anoying.So, is there something I missed?Regards,Arnaud Solvay, LFPG
