I apologize for the delay in releasing the sponsored chapters. Due to the chapter size $20 per sponsored chapter is just too low. So depending on the novel, $20 will be enough for half a chapter instead of an entire chapter.
I will be releasing one of the Game Market 1983 Sponsored chapters in a few hours, three sponsored chapters for $60 is just too low given the chapter length.
Moving forward for novels like this, it will be $60 for 1 and a half chapters.
