CData Connect AI

I am using Connect AI to pull some data but I am missing some Tables and Columns that exist in the data source.Where can I find them and what can I do to make sure that I am getting all of my data? 

There are many other data connectors from other companies that connect with PowerBI. What benefit does the PowerBI certification for CData Connect AI bring? 

I’m facing a timeout error when executing queries to tables for a given connection in Connect AI. The error message is as follows: [ERROR] Execution of the SELECT query failed. Error: Timeout when wait response.I tried to increase the Timeout value in the connection Advanced Settings tab, but nothing changed. What should I do? 

I can't find the verification email to verify my Connect AI account. It's not in my inbox, or in the Spam or Trash folders. How can I verify my account?

I am trying to query my sources in CData Connect AI but they are running slow. They used to run instantly.What can I do to return to the speed the queries were running with?
