Contact disappears from Zoho CRM when fetched again

Contact disappears from Zoho CRM when fetched again

Hi

I imported my contacts from Zoho CRM to Zoho Invoice with ZSC key which worked fine.

I then edited contact details in Zoho CRM for a contact.

I then selected in Zoho Invoice " Fetch again From Zoho CRM"

The record has now disappeared from Zoho Invoice so I can't fetch details.

Please can you explain.

Thanks

Gene
