Sync Contact between CRM and Desk / Support

Sync Contact between CRM and Desk / Support

Hello,
I have set up Zoho Desk and CRM integration. I have the ZSC key correct. Zoho Desk is adding to the CRM but Desk is not pulling in CRM accounts so Desk is only adding to CRM. I have over 900 accounts in the CRM and only three are showing in Desk and these were added by an agent.

Two way sync shows Desk to CRM but no CRM to Desk activity.

Any assistance would be greatly appreciated. As an aside, I waited for 47 minutes on the support line as "caller number one", not sure if that is normal, first time calling.

Thanks
