Thanks for the link. I see that you add videos from Dailymotion and have configured our plugin to play using our custom video player.
Unfortunately, the Dailymotion JS SDK that we use in our plugin has been deprecated by Dailymotion recently. I’m not sure if this is making any difference.
Solution:
Kindly go to the “Video Gallery => Settings” menu from your WordPress Admin Dashboard, find the “Use Native Controls” settings, check the “Dailymotion” option, save the changes and check now.
In case the issue remains, kindly enable the “Force JavaScript Based Initialization”, and the “Lazyload” options from the same settings page and check again.
Hope this solved your issue!
