Would it be possible for edits coming in via Sync to be updated by attribute instead of by row for ArcGIS Online hosted feature services?
We have issues with field users taking Collector offline in the morning (and updating certain fields) overwriting bulk updates (on different fields) done in the office when they sync at night. Examples of the issue are provided in the GISS Workflow here as watch-out situations.
Having a mechanism to allow for multiple offline editors to touch the same feature without guaranteed data loss would be a major improvement for us.
