Unable To Embed Our Video Player Using Upfront Editor? Also Unable To Edit Lightboxes


The following doesn't work when I attempt to embed the following code in a code element:

<script type="text/javascript" src="http://integrion.evsuite.com/player/aG93LXRvLW1ha2UtbW9uZXktd2l0aC1kdWJsaS1qY2MtMjdqYW4yMDE3LWlpLTAwMS4ubXA0/?responsive=1&autoResponsive=1&container=evp-MMMJX8B02R"></script><div id="evp-MMMJX8B02R" data-role="evp-video" data-evp-id="aG93LXRvLW1ha2UtbW9uZXktd2l0aC1kdWJsaS1qY2MtMjdqYW4yMDE3LWlpLTAwMS4ubXA0"></div>

This works just fine in a non-Upfront theme, like Twenty Seventeen.

It would appear that one is also unable to edit or delete their light boxes once they are created.

Really had high hopes to use WPMU Devs Upfront-based themes on our new WPMultisite. Are these themes really that broken? Really hoping that I'm the one who is doing something incorrectly since I'm new to the Upfront Editor.

Please advise.
