interactive book

I am adding videos to image hotspots in an interactive book - https://stchas.h5p.com/content/1292114305122122238#h5pbookid=12921143051...

On some videos there is a fog at the bottom

The videos are not all the same, in terms of video window for viewing.

This is happening in H5P (Desktop) while I am working on the interactive book. Not after I upload it to Canvas

My interactive books no longer load correctly on the H5P online editor or logiquiz 1.00.11 (with the H5P activities updated), all activities have disappeared. However, I can open the H5P exports on an old version of logiquiz with the H5P activities not updated. What's going on please?

Hi,

I am using the Interactive Book on Brightspace and I want to add some of my colleagues to the H5P content in order for them to edit/see reports and change ownership. Sadly it seems impossible to find my colleagues when I fill in their names at 'collaborators'. I can't find them with their name or their email addresses, but they are members of the Brightspace page. Anyone that has any tips on how to share the content? 

Thanks in advance!
