The situation is the following:
When activating both below settings to YES:
Import downloaded images into Media Library? Yes No
Enabling this option will import your auto-downloaded images into your Media Library.
Set first imported image as featured image? Yes No
Enabling this option will use the first of your media-imported images as a featured image for your status update.
Note: Media Library import needs to be enabled too.
Then here is what happens as a result.
When I post a link while it works out nicely at the preview and while at publishing it display rightly the link in the post the preview link thumbnail and also preview text it actually displays in the post (ul) are the featured image and preview text of the earlier posted link which it uses as featured image and text.
This happens everytime when these settings are set to yes. When publishing a link it includes the featured image and preview excerpt text of the earlier posted link which it goes fetch and publish altogether with the newly posted link.
(Note I did solve the feature image issue above with another plugin BUT the preview text excerpt issue is going on.)
