All of my embeded videos started showing this statement"Provided ID could not be validated." in place of the preview that was there previously.
Topic on Extension talk:YouTube
Found if you add the /youtu.be in the tag
<youtube>/youtu.be/x-XXxXXxxxX</youtube>
you get a frame with a button to Load the Video and then caution you about YouTube collecting personal information
Is there a way to go back to the preview?
