Interactive Video

I have a strange error, with H5P, and after much, much, much research, I stil don't have an answer...
we're using Moodle 3.5 as a platform, but... upgrading to 3.6/3.7/3.8 did NOT solve the issue unfortunately.

Reaching out to the community for the much appreciated help!

what's the issue(s):

1: interactive video not (allways) playing:

Dear All, 

I have learndash and tincanny on a wordpress, i am trying to use h5p on top of these platforms. When i add a piece of h5p content (interactive viedeio) it doesnt show up on leandash and the consoul of the browser throws these errors. 

The captions track is hidden by interactions added to the videos (pop-up boxes) and causes a web accessiblity issue. Captions added to videos are intended to make the video and also make it more accessible to viewers who may suffer from hearing issues and others.
