The basic problem is that the Kobo refuses to load some ePubs, freezing the gadget while Processing Content (sometimes wrecking everything and necessitating a Reset) while declining to specify what it doesn't like, offering fixits, or just skipping the bad book.
The latest: after seeing the Masterpiece version of Dickens' Edwin Drood, I sought out the PG edition plus two related titles there. I also got MS Word to save the Wikipedia article on the book as Filtered Web Page, then got Calibre to pick it up and convert it to ePub. Well, one or maybe all of those 4 ePubs snarled the KT. I tried this and that and the other thing--all too tedious to relate--but now it looks like I'm doomed to a Reset...for maybe the 5th time in a year.
Why can't the Kobo folks add a function to the desktop app that examines ebooks the user wants to put on the KT and says either Go Ahead and Load It or Something Wrong With That ePub?
I suggested this in March and am peeved that this company doesn't seem to pay any attention at all to the numerous loading problems that users experience, as can be seen from the traffic in this forum.
Are you there, Kobo?
Are we ever going to get a firmware update?
