ChalkySticks TV requires your browser to be able to autoplay videos. Unfortunately, Safari 11 no longer supports this feature out of the box. There are two solutions:

1.) Use a different browser

We encourage the use of Google Chrome, Opera, or Firefox for an optimal experience and better performance.

2.) Enable "auto-play" for this website

In the Safari dropdown menu, find Settings For This Website.... Find the setting Auto-Play and change the value to Allow All Auto-Play then refresh the page.
