On Chrome OS Photoshop Web when download auto. the img. save as a zero bite file instead of an img.

On Chrome OS, Photoshop Web beta when downloading by hitting a button (without changing settings) the image save as a zero bite file instead of an image Which was really confusing It would be preferable if it prompted you to choose what kind of file you wanted to save this because seeing it as a zero bite file unless you manually changed it in settings is it confusing and not intuitive
