CRM / Desk integration

CRM / Desk integration

Hello all.  I'm going thru a trial of several Zoho products, mainly CRM and help desk.  Am I correct in assuming that if I add an Account and/or a Contact on the CRM side, this would automatically sync over to the Help Desk portal?  It doesn't seem to be working, at least not very well.  I have one Account with two Contacts attached.  I did a manual sync, and after about two hours they came over.  However only on the web, not on the mobile (iPhone) apps.

Is my thinking correct?  The #1 reason I'm trying out the Zoho tools is to keep all my client information updated across the board.

Thanks!
