In my library, two ebooks still have no download option. One is no longer available, and the other is a graphic novel which is probably in Kobo's own proprietary format.
What about your Kobo library?
I would really like to get feedback from Kobo customers, because Kobo hasn't announced the technical fix yet and so far as I know the issue was only resolved in the past week or so.
As I look back at my past coverage I see that the download issue was still present as late as the 17th when a commenter noted that they had to use the workaround I posted in order to download the DRM-free ebooks they had bought.
Speaking of which, if you find that you still have ebooks with no download option there is a solution. You'll first have to download the ebook with the Kobo for PC app, and then you can use a 3rd-party Calibre plugin to transfer your purchased ebooks to calibre. (This is a different workaround than the one required for Nook ebooks, which still suffer from blocked downloads.)
That plugin will also convert the ebooks to the standard Epub format and strip the DRM so the ebooks can be read on any device you like.
So, can you download your Kobo ebooks?
