Hello Abular,
Greetings !!
Could you please provide us with the thumbnail image and the YouTube video link so that we can check this on our end?
Additionally, it would be helpful if you could share a screenshot of the email notification, indicating the desired position for the thumbnail. Please include the name of the email notification as well.
This will allow us to review the situation more effectively and provide you with appropriate assistance.
Thanks & Regards,
Mukesh
