My Kindle App on my iPad no longer saves the location locally of books I am reading. If I am reading a book purchased from Amazon, it works. But If I am reading a book that was an EPUB and then I converted it to MOBI, using Calibre, it doesn't save the location. I can take the same MOBI file to a Kindle for Android and it works fine. This function used to work in the iPad until a few weeks ago.
Any ideas?
