I have a questionnaire that may take a couple of hours to complete and will be send to 20 000 of random respondents (anonymus, without ArcGIS Online account). They are expected to fill it in using web browsers on their computers or mobile phones.
Can a person save the partly filled in questionnaire and get back to it after some time?
Is it possible to assign a personal code for a respondent that will allow reopening the partly filled in survey?
Thanks,
Natalia
