Updating the category thumbnail image, new image doesnt appear in the community?

Yesterday I updated the thumbnail images to a few categories. I noticed that the images were not updating to the community. I thought there might be a delay but they still haven't updated.

Maybe this has something to do with Control's new look?

I confirmed today that in the Control new thumbnail images can be seen. I have tested with other browsers as well, with normal and incognito mode.
