Would it be possible to attach a pdf instead of a jpg inside survey123 application. The idea would be to have the person use a camscanner type application then attach the document to a survey.
I can see that it is possible through the survey123 desktop application, however the android survey123 only returns images.
I suppose if the extension .pdf was modified to a .jpg it could work.
We do not currently support adding PDF attachments to a survey via the Survey123 app. We have an open enhancement request for this functionality and I have updated the issue with your comments. This is something we hope to support in a future release of Survey123.
