I use Survey123 for ARCGis on an Android 8; I was going over my sent data for a survey I'm working on and accidentally emptied the sent folder. Is there any way to recover this sent data? This survey was not connected to my ARCGis Online account; however, I've found pictures from the sent data on my phone, so maybe the lost survey data is still in there? Any assistance would be much appreciated.
Although it is not possible to retrieve Sent surveys that have been emptied from the Sent folder, it is possible for the survey creator to enable the Inbox using Survey123 Connect which can be setup to allow you to re-download the surveys which you have sent, edit them, and re-send.
