I know that Chrome 66 introduced some restrictions when autoplaying a video (in HTML5). In some cases the autoplay is supported. One of the conditions to support autoplay is when the user has watched a video in the domain before or something similar. So Chrome is keeping an internal score for each site. This score can be checked in chrome://media-engagement.
But now my problem is that for testing I have not figured it out a simple way to reset this score. So I can not properly test it for the new users.
Any idea?
The easiest way I found to test using a clean score is to create a new profile in Chrome:
1- At the top right of Chrome, click the button with your name or People People.
2- Click Manage people.
3- Click Add person.
4- Click Save. A new window will open and ask you to sign in.
