Bugs in content types

Hi all, I'm very new to H5P. 

Just tried out an interactive video, when playing in Firefox it's OK; but not in Chrome or Microsoft Edge. Both show "video player loading...". I've seen some older threats on this, but don't seem to get a solution.

I'm using H5P for SCORM. Hope to get some lights here.

I have one reader that can't see the timeline I have inserted. All other readers. What is causing this one reader to not see it and how do I fix it?

Hello

I have a little issue if you can help me please. I created an h5p interactive video with a question that is graded and the gradebook is correctly set up. When I test it by submitting the answers from Moodle app (student account), the grades were not recorded in the gradebook but when I logged in from the browser not moodle app, the grades were recorded successfully. So can this issue be solved or is it already addressed to be solved in future updates?

Thank you!
