Course Presentation

When I updated to CKEditor5 in the Course Presentation, I noticed that the creation of interactivity slowed down, ie. it happens that the browser suddenly blocks. Does anyone have a similar problem in Presentations? No errors in error log file.

I created and saved content last night but this morning content is missing. I saved and copied the content to clipboard but now its missing. How do I find my content?

I use interactive books fairly frequently, and I have included Course Presentations within an Interactive book before. It seems like it's no longer possible to do this though, the option under the "add content" menu no longer includes course presentation. Is there a fix for this or was it an intentional removal for some reason?
