If you are a premium user, I recommend the following: 1. Open the app settings. 2. Choose offline Notebooks. 3. Check off whatever notebooks you want to be cached on the device. Now, whenever you choose sync from the options menu, or the app syncs in the background, it should also download the content and resources for each of the notes in the selected notebook. It'll likely take a while to complete the first sync after you make the change.
