When an offline package is downloaded it includes the offline layers along with the map definition (.mmap file) which includes information such as forms and popups (including the arcade expressions). We have found many cases when a minor change is required to the online web map. Currently, any minor change to the online web map requires the entire package to be re-downloaded. This can be quite inconvenient to almost impossible in some scenarios.
What would be incredibly useful is if the SDK provided map update functionality. This would consist of updating the mobile_map.mmap definition for the pre-packaged area based on the current web map without requiring a full download. With this functionality, fixing an arcade expression in the web map would no longer require the work force to download new packages
