Published paper not showing up on google scholar
In a blog post, Claus Wilke describes a bug with Google Scholar where it does not update pre-prints once the article has been publsheed. He notes that:


  
  The bug exists
  The Scholar team is aware of it
  They don’t know how to fix it
  They don’t think it’s a particularly pressing problem
  For any given paper, the problem will go away eventually, after several months or more
  


The other answer by cirne recommends that you upload your own citation. This will update your Scholar Profile but not Google Scholar. Thus, your profile will be correct, but others cannot search Google Scholar to find your papers.
