Data4Action has been designed so you cannot switch a survey back into Edit Mode after your survey has been purchased or published. However, Data4Action does have a process for editing a published survey. After editing a published survey, results collected from your original survey and results from your republished survey are stored in separate files in your Data4Action account.
If you wish to edit a published survey you will need to copy desired survey and make your changes on the new survey and assign devices again. Noting that your submitted data will be fragmented into the old and new survey.
We recommend you test your survey on a physical device before publishing or purchasing a survey.
