Analytics <-> Invoice Connection DELETED by Zoho

Analytics <-> Invoice Connection DELETED by Zoho

Hi All,

I am reaching out today because of a big issue we have at the moment with Zoho Analytics and Zoho Invoice. 

Our organization relies on Zoho Analytics for most of our reporting (operationnal teams). A few days ago we observed a sync issue with the Zoho Invoice data source in Analytics. The error message is pretty scary: "The selected organization xxxxxxxxxx in Zoho Invoice was either deleted or revoked."

It seems to be linked to a 120days inactivity in Zoho Invoice. We do not use it (we use Books). But the data source is synced daily in Analytics, and we rely heavily on it !

At this time, we are unable to log in to Zoho Invoice. It redirects us to Books immediately. 

This integration is super important to us: we have a large quantity of SQL queries, tables and reports that are linked to Invoice. We really need it restored. 

The Zoho Support gives pretty empty answers like "We recommend using Books". 
Do any of you have had a similar issue, and how did you solve it ?

Many thanks for your help !
