Hi,
I have a page with an image block set up with the image size set to “medium” on the block settings page.
When I run the page on Page Speed Insights I am getting a warning that says “Properly size images” and references that exact image is being served as the full size version of it, but the block setting is set to “medium”.
Therefore I do not think the image block is working as it should.
below is the page for reference and the image is the first one you see on the right side above the fold.
