Bugs in content types

I've been making a tutorial using the branching scenarios and interactive videos and I've run into a few problems.  Maybe some of you can shed some light on it for me.

I've pretty much completed it and when I was previewing the course, I would intermittently get a screen that stated either "video not supported" or "unable to decode media."  If I refreshed the browser, the video would work and then maybe a different video would state the error. There was no rhyme or reason that I could figure out.  

Hello. I have a problem with multiple choice question. I looked the multiple choice tutorial and I noticed "Media Section" is missing in editor. Because of the fact that, the page is not saving when I clicked the save button. There is an error message in console. I tried this in firefox and chrome, stuation is same.I added the console image and editor image.

Moodle version: 3.7

Platform: Desktop

H5p Version: 1.18

H5p content type: multpile choice/ multiple choice in course presentation

Hi,

It seems that when you use the Twitter user feed content type, regardless of which Twitter user you specify, it will default back to @TwitterAPI

This was first discovered by one of our users on our Moodle site but I have now confirmed that it also affects activities created directly on h5p.org.

Presumably something has changed on the Twitter API.

Many thanks,

Richard
