Hi David,
There’s nothing you should have done differently. Currently, the app is designed not to automatically sync PDFs from your web library down to the iPad. This was done in order not to consume too much storage on the iPad – some users have several gigabytes of PDF attachments – and also to save time and network usage during sync.
In order to get individual PDFs from your web library onto the iPad, you can either (1) tap the “Not yet downloaded” icon in a reference with an attachment, which will download the PDF for viewing (but will not permanently store it on the iPad), or (2) mark a reference as a “Favorite”, which will ensure that any PDFs attached to that reference are downloaded during sync and stored persistently on the iPad.
There is not currently a global setting to control whether or not PDFs sync to the iPad; rather, this is controlled by the mechanisms described above.
We are definitely hearing that people want an easier way to download their PDFs to the iPad (i.e., without having to mark each reference as a “Favorite”), and we’re working on improvements in this area for an upcoming release.
Thanks,
