I use the news feed web part on my company's intranet homepage. Over the last week, the thumbnails of the news posts have stopped displaying, instead using the default "no image" for the thumbnail. When looking at the post properties while editing, the correct thumbnail is uploaded. It just doesn't display on the feed.
I've tried removing and reuploading the photos, but this has made no difference. I have tried using other means of uploading the photos but again, the feed itself does not display whether I use a URL or an uploaded image. Are there any solutions to this?
