I'm not sure how often this happens with Logos, but I have a some CP items that seem to be live products on the logos website, but are not in my library on my PC or my iPad (have not checked Mac).
It's hit or miss on which of the products have been downloaded and which are missing.
All the emails start, "We are about to begin processing Pre-Pub orders for <Product Name>. This product is scheduled to ship on <Date>."
