Could this be a bug?
If not, where is the configuration located to remove the extra URL displayed?
For example: if a member submit a youtube link it shows:
the unformatted youtube URL
ES link to youtube
thumbnail video with description
I tested this using the demo and I've attached photos to explain
es1.png = default ES
es2.png = request to remove extra URL for cleaner look
es3.png = how about full video embed?
