Hi all, I have a Kobo and use Calibre to sideload with no issues. My partner reads on the Kindle app on his phone. I used to be able to convert books to .kfx in Calibre, transfer to his phone documents folder, and he could open them with no issue. In the last few months I've been trying on and off to load books for him with no success. Any advice would be welcome and appreciated.
