I have had the same problem. I would make a new thread but your depiction of the bug is incorrect in this thread. It does not publicize to Tumblr when you are only using a featured image. It was publicizing the featured image three weeks ago when this thread started but now it does not at all. I’d like help getting my featured image to post again on Tumblr since I, too, only use the featured image aspect in my posts.
