Table and Matrix Visuals Not Appearing In Report

[stevenamani]

We are using the JavaScript Client API to embed reports. Since last week, we have been an issue where table and matrix visuals sometimes do not appear on the report (the title appears) and the Rendered event never gets fired. There are no errors in the browser console. Can anyone shed some light on this? Our clients use these visuals extensively and this is affecting their business so a quick resolution would be much appreciated.
