Very slow to update from the CRM module to our Support module

We use Zoho to track our Technical support for our customers. When we set up a contact in the CRM that works normally. However it is taking over an hour for that contact to show up and be available in our Support module so that we can open up a support case for that contact.After about an hour the contact is available to be added to a new ticket.
