I uploaded the Media File. I included feature service access using search() function . i have a requirement that, if the device is offline , it automatically pulls the data from local media csv file . if the device is online, it pulls the data from actual service data. few people suggested that, use "Linked content with CSV" and update the CSV content regular periods . How this works and is it possible to update local copy of csv file using Python API ? Will fieldworker get any notification that, your Linked content CSV updated please try to download latest copy of it? I did not find much documentation on it.
