A reader notified me of an error with a pronoun ("he" instead of "it") in Chapter 22 of the novel "High School Massacre." I fixed it and re-uploaded the novel to Bookapy and Amazon KDP.
If you previously purchased the novel and want a perfect copy, you will need to download it again. I believe the upload to Bookapy takes effect immediately, but I'm not sure. I uploaded the corrected novel to Bookapy last night (around 8 hours ago). I just uploaded it to Amazon KDP which takes several days to take effect.
Most authors wouldn't bother notifying you of an error, especially one so small. I'm not one of them. Even though I sometimes find errors in traditionally published bestsellers, I expect my stuff to be perfect.
Sorry for any inconvenience.
