I am testing the WebEx VILT integration and I need the session time to open 15-30 minutes prior to the session starting but the Virtual Event set up won't save it. It keeps changing it back to 5 minutes.

Oracle Support says it is a WebEx setting. I can't find it in the WebEx Administration Site settings. The WebEx help documentation says it can be set in the templates but the LearnCenter integration doesn't use the WebEx templates, does it?
