Bugs in content types

Please advise how we can identify where libraries and content are used in our LMS and how we can delete library versions, etc.

I read the library administration page and comments looking for instructions on how to identify where libraries were used before deleting or upgrading specific versions of libraries.

Libraries cannot be deleted if they have content and we cannot easily see where the content is.

Hi,

I tried to use H5P content on my website but it seems not to display properly. It is cut on a website view and cut even more on a mobile version.
I'm using the newest version of Wordpress and 1.15.0 H5P.
