Course videos not playing on Ipad or Iphone IOS10.1?

Hello!

I am trying to view courses created in Storyline 2 via Cornerstone LMS and the courses that have videos are not displaying correctly on IOS.  We are publishing to html5 as Scorm 1.2.   They launch on android and on desktop and work perfectly.  They are very simply designed courses - .wmv videos dropped into a slide with some basic triggers - occasionally the video slides are broken up by a couple "check your knowledge" quizzing slides - but that's it!  We cannot use the Articulate Mobile player at this time, but even when I did test it on AMP, I was experiencing similar issues.

So, 2 different things happen depending on how I have the triggers set-up. 

1. If I have the trigger set to "jump to next slide once media completes", the video never plays and skips right to the next slide within a second. 

2. If I have the trigger set to "jump to next slide when timeline ends" the timeline plays thru, but just as a blank screen, no audio and no video. 

The properties are set to advance by user as indicated in this article: https://www.articulate.com/support/storyline/audio-or-video-is-missing-in-mobile-safari and I've read through everything from these discussions: https://community.articulate.com/discussions/articulate-storyline/videos-do-not-play-on-ipad-with-articulate-mobile-player
https://community.articulate.com/discussions/articulate-storyline/issue-with-movies-playing-on-ipad

So not sure what I'm missing.  I even went as far as to rename the video files with no spaces or special characters.

The course operates correctly within Safari from Scorm Cloud, but not Cornerstone. Cornerstone has a mobile app and the courses won't work properly within that either.  But again, all is well via scormcloud when viewed in IOS thru Safari. 

I just want to be sure there isn't something I'm overlooking in the development and publishing as it relates to functionality via an LMS in conjuction with IOS when there are videos involved.  Can someone take a look?  Some of the video slides are set-up with the trigger based on timeline ending (2 above), but some video slides are set-up to jump to next slide based on media completing (1 above).

I really appreciate it!  We have over 300 courses to move to this new LMS and a mainly mobile workforce that has to be able to view the courses on IOS and no matter how I slice it, I can't get the content to work properly.
