I'm wondering about the offline capabilities of DPS 2015 apps... How does new content appear? Does it pop up automatically when a user is online? Do we send push notifications for them to manually update? Is old content available when offline? Etc etc... Any other info on this would be helpful as well.
It's the same as what you see in the preview app, although the time between when you click publish in the portal and when it is available in the viewer is longer due to server caching.
Users will see an update notification whenever they come into a collection browse view and we detect changes on the server. They can either tap the update notification to apply the change or we will auto-apply it next time they come back to the collection. Content previously viewed is cached offline and cleared out as needed with the oldest viewed content removed first.
