Gutenber Video Issues

1) When I select a post image for my videos, it somehow goes back to finding an uncompressed version of the image, so my page is super slow. Maybe this could be solved by not uploading an uncompressed image to beg with, I have used the smush plugin to compress all my images and it still is finding the uncompressed version of it.

2) If I remove the post image for the videos, it shows a preview in the desktop version, but not on mobile. So I get a fast page now, but no post image on the videos.

3) Seems to have issues with larger videos, I have to upload them to my server directly, and then it loads fine. I can’t upload larger videos to the site directly.

4) It’s not sizing itself correctly in mobile version, it’s smaller than it needs to be.
