I have an issue when I publicize a post to Facebook using Jetpack Publicize ... it's like Russian Roulette ... sometimes it uses the correct Featured Image I have designated ... sometimes it does not ... when I run the URL for the posts in question on the FB Debugger ... it shows the correct Featured Image ... with no errors ...
Conversely, if I manually share the post to my FB page, or if I use the jetpack FB share link at the bottom the post itself ... it always uses the proper image.
