I have an AGOL feature service with missing point data. I believe it was accidentally overwritten. A mobile user however, has the point data in their collector application. Can I recover point data from this?
I understand that your original data was overwritten on AGOL and you are looking for a way to retrieve that data, you mentioned that there is a Mobile user has the same original data in Collector For ArcGIS. The services for application (Collector) is it also hosted on AGOL or ArcGIS Server?
Either way the data should be accessible or there will be an option to download it and can be replaced to the original service.
I hope this helps!
