Yes, the issue started two or three updates ago.
When I set a picture as the shutdown cover, it stays the same even when I replace the image. The sleep cover only updates if I select an image with a different file name. This prevents KoReader from automatically saving the cover of the current book I'm reading, as it keeps replacing the image without changing the filename.
My device also isn't rooted. I've debloated it and keep it offline.
