I see, that is very weird indeed. Alright, well one of our developers might be able to help. Just be sure to mention it in the ticket itselfYes I am - actually all my posts do have featured images already. I've tried to add new posts with featured images as I assumed it's maybe not working for old content but that did not change anything.
My settings in Style Properties for XPress are:
I've attached a screenshot of one article in Wordpress (it's the most recent version 4.9.8).
- Article List Layout style: List
- Article thumbnail size (for list style only): Medium
The featured image also does show up in the header of the article as well as on Wordpress as a featured post, just not in the list.
As mentioned, I'm only using the Xpress addon and UI.X.
