Unable to view Contacts on iPad app

Unable to view Contacts on iPad app

I'm using the Zoho CRM app on my iPad but it only ever wants to sync a small portion of my Contacts.  I have about 3300 contacts, which I can view online just fine, but when my iPad tries to sync with the main server/main account it only pulls maybe a few hundred of those contacts, at the most.

My Zoho App is fully updated.  I've tried uninstalling and reinstalling the app, I've tried resetting the application and re-syncing the data, and I've checked all of the settings to make sure contacts aren't being hidden somehow.

Please advise!
