Hi Michael,
That’s certainly strange! Let’s dig in here together and see why those images are not importing.
First off, I tried importing an event from Facebook without Events Calendar PRO active and the featured image appeared to import correctly. Here’s a quick screencast I put together that shows how I tested it out and the featured image displayed in the event editor.
Are you seeing the same thing when you try importing? If not, would you be willing to share the Facebook URL you are importing from and an example of an event where the featured image is not being pulled in at the same time? That would be super helpful!
Thanks so much,
Geoff
