I’m having the same issue and it seems to be related to image size. Deleting and uploading the image multiple times will eventually get one where I can see the preview.
Same issue here. It seems that for files large than around 5 mb, it sometimes doesn’t render a thumbnail/preview on the first try, and I have to delete and upload the file multiple times to get the preview.
