I am trying to add interactions in my embedded youtube video but unfortunately since the 3.9 update, the bar on which the clickable interactions are located are no where on the screen...
If it works in one browser, but not another, then it's almost certainly an issue with H5P itself, rather than H5P in Moodle, in which case you can report this to the bug report forum: https://h5p.org/forum/9
