I am working with the most recent Survey123 applications (Survey 123 Connect 2.1.9) and the iPad app 2.1.6. I created the survey in the online survey builder (survey123.arcgis.com). The problem occurs when I have published the survey, turned on "Inbox" feature, downloaded responses to my iPad and want to EDIT those responses from the iPad. When I "send" the edited response I receive error "Code 1000 Must declare scalar variable @ObjectId".
I don't understand this, since there is no problem creating new surveys, only a problem updating existing ones. The ability to edit surveys in the field is the only reason we are using Survey123 and if there is no work around for this, can someone suggest an alternative to Survey123 that allows editing existing surveys in the field?
