No contact sync with iPhone5s

Hi Zoho Team,

i have a problem with the sync of zoho contacts on my iPhone5s. I have two accounts on the phone. A  business one , with notes traveler app and zoho as exchange, push is enabled. I set zoho as standard account for mails and contacts. Yet when I add a contat it ist not in zoho (web) . Could You help me please?

Thanks in advance.
