Uploader name

when it doesn't that means they uploaded chpters through imager flow..not directly from upload button

It means chapters were aggregated from other sites cuz sites like mago are like chain with link they automatically collect any sources with their similar link that's why uploader name is not shown . (Btw Imgur system doesn't work they tell to use upload button directly)

really..i thought it's still working

Nop I tried this method they reply back saying use upload button instead.

awww, I see. Thank you.
