when publishing to Facebook from indesign cover photo jpeg from advanced tab doesn't show up on face

Running Mac OS Big Sur 11.7 

InDesign 18.0

When publishing online to Facebook from InDesign like I have done dozens of times before with no problem, the image I select in the advanced tab of the publish online menu does not show up on Facebook. This changed about 2 or 3 months ago. It will publish my article but the image space on Facebook is blank. I have uninstalled and reinstalled InDesign, deleted preferences and still no change. What can I do to make the image show up on Facebook once again.
