title_body: I only see the download links for DRMed ebooks on my Kobo Library
upvoted_answer: So I messaged Kobo's customer service and got this response
  
  
    Thank you for contacting Kobo Customer Care. We are more than happy to
    assist you.
    
    The book(s) you have purchased have been released by the publisher in
    the new ePub3 format, which can only be synced through the Kobo cloud.
    If you are not using a Kobo device or application, you will not be
    able to add this book manually. Additionally, ePub3 books are not
    compatible with some of our older Kobo devices such as the Original,
    Wifi, and Vox, nor the Kobo app on a Blackberry device.
    
    We apologize for this inconvenience and would be happy to offer you a
    store credit or refund. Please reply to this email and let us know
    which you would prefer.
  
  
  I thought ePub3 is a standard? But I guess that's another issue entirely. At least now I know why those download links were missing.
