Embeded youtube files does not work

[VerNovo]

Behaviour: Embeded youtube files shows correctly in editing (for example: area of text), but after saving there is blank space and code is missing in content (perhaps issue where <iframe> is deleted)
Where: just in sections!!!, everything is fine in introduction
Recreation: go to section > create area of text > in source code paste the code for embedding > save and go to that section > blank space
Notes: the same embed code works fine with different course formats

Hi

We're having the same issue

Is there any work around or plan to fix the plugin at any point? At the moment we can't use this course format as we use YouTube videos in course sections
