I set a video (.mov or .mp4) in the home page.
I tried it in local, and it worked.
After the deployment, I could not see the video (it appears only on a coloured background).
The same is about the Twitter timeline that is an HTML code as follow (I changed the twitter username with user):
<a class="twitter-timeline" data-width="600" data-height="800" data-dnt="true" href="https://twitter.com/user?ref_src=twsrc%5Etfw">Tweets by user</a> <script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>
Are there issues with the mobile?
