I see the images in your feed, but perhaps they don’t like the responsive images code added by WordPress, seen in the srcset below:
<img width="300" height="161" src="https://neavision.it/wp-content/uploads/2019/07/webmagazine-min-300x161.jpg" class="attachment-medium size-medium wp-post-image" alt="webmagazine" style="margin-bottom: 15px;" srcset="https://neavision.it/wp-content/uploads/2019/07/webmagazine-min-300x161.jpg 300w, https://neavision.it/wp-content/uploads/2019/07/webmagazine-min-768x413.jpg 768w, https://neavision.it/wp-content/uploads/2019/07/webmagazine-min.jpg 1024w" sizes="(max-width: 300px) 100vw, 300px" />
Feedly may require larger images of a certain size:
“If the first img in the story has a height and width greater than 450 pixels, that first image will be selected as the featured image. If not, Feedly will try to pick the largest image in the story.”
