I'm trying to send Heiser's 'Unseen Realm' to my Kindle - I bought it in Logos rather than Kindle for the tagging etc., expecting to be able to send it to my Kindle to read through as I do for most of my theology books when I want to read them rather than refer to them. I can open it on my iPad and Android phone, but can't send to Kindle.
Is this a limitation on the particular title?
