"Advanced Layers need to be enabled to use Camera" issue while doing Adobe Animate tutorial

[Patrick26274948k0vp]

Am new to  this forum and a newbie with Adobe Animate - am undertaking Adobe Animate CC 2018 release - Classroom in a book and in Lesson 7 which covers using the Camera - find the camera tool greyed out and if I click on it I get the Window tip - "Advanced Layers need to be enabled to use Camera" cannot find any reference anywhere on this message and why the tool is disabled and unsure if this is a program issue or maybe an issue with my PC not meeting the system requirements although all else seems to work ok.  Any help appreciated

OK I did find you can set under Document Settings - a checkbox for 'Use Advanced Layers' as outlined by Youtube video near the start - https://www.youtube.com/watch?v=hhGgHVAZIwg
