We have a non-federated feature service published through AGOL to use in ArcGIS survey123, the surveys are updated in the inbox and are edited in the field via survey123; once edited they are sent (successfully it seems from Survey123; ie: do not get stuck in the "Outbox", but are in the "Sent" box) however the database is not updated to reflect the updates.
Our layer is setup in a feature service with Archiving on, we used to have our data versioned, but with the last update to Survey123 had to move away from it. Now, for the first time, our archived data seems to not be sending the updates to the server from the field workers.
HELP! We have potentially lost a week or two of work.
Which version of Survey123 are you using? Can you attempt a edit/submission session with logging engaged to capture the network traffic (see Troubleshoot—Survey123 for ArcGIS | ArcGIS and simply start logging without connecting to a console).
