I have selected all 3 options - featured image, first image content, and blank image holder. Reordered so that first image content is top choice. Only featured images will show in the grid. I have tried to watch the you tube tutorial, but is very fuzzy and unwatchable. I have deselected the featured image selection and then I get either nothing or the placeholder. I want to have the option of using either featured image or first image in content.
Welcome to our forum.
have you reinstalled the pro version? this might be cache issue, please deactivate any cache plugin or try clear browser cache.
Please create a new post grid and try the media source option and let me know the result. in pro version, you should see many other options.
Let me know the result.
