Kindly note that almost every automatically played video will be muted, regardless of the settings in Spotlightr.
Settings for Auto-play Video are located under the PLAYBACK OPTIONS.
To activate this feature, just turn the toggle on to Enable and check desired boxes to control how and when the video auto-plays then click on the SAVE button.
Autoplay only on first visit - Just as it says, video will autoplay only on the first visit by a viewer. Once that viewer closes the page and returns to the video for a second time, it will not autoplay.
Reset video when unmuted - Once the viewer clicks the "unmute" button on the video, the video will reset back to the beginning and play from the beginning.
