Comment Comment by captn3m0 I suffer from the same issue. I use KOReader, which does do sync, but uses its own zsync protocol, which basically nothing else supports.I use Kybook 2 on my iPad. I think Calibre supports syncing with Kybook 3, so you could try that.If you really want highlight syncing etc, it might be worth migrating to a Kindle-first workflow? But PDFs aren't there.Why is this so hard :( Why can't everything use a standard progress sync protocol?
