All Platforms add EXIF data to the file.
Photo orientation is included in this. Here J scrubs all that data out first before it even hits the servers. This is a feature, not a bug, for security reasons.
Now the way to fix this is take a photo, from your camera on a smartphone or a file. Open it in any photo editor, does not matter which one. and make any small edit, any at all, crop, or enhance color, anything. then save that edited photo. Then up load that to CoSo.
