Hi NikHil,
The plugin was active, now that I de-activated the plug-in the website looks like normal again. Also, as I understand it, the plugin is also active on the store overview since it is possible to have the video as a thumbnail on the overview.
I’m using services like autoptimize and a cache in order to speed up my website. Might those have caused that the plugin seemed inactive to you? If so I can deactivate those and re-activate your plugin so you can check again.
