 * When the “Replace Youtube videos by thumbnails” function is enabled, thumbnails
   are replaced. However, the sketches are too small. For example, for a page [https://ldesign.studi](https://ldesign.studi)(
   the most recent block at the bottom) the thumbnail for the video looks like [https://i.ytimg.com/vi/w5uVCsDXUw8/hqdefault.jpg](https://i.ytimg.com/vi/w5uVCsDXUw8/hqdefault.jpg).
   Why is the sketch so small?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Finvalid-thumbnail%2F%3Foutput_format%3Dmd&locale=en_US)
