How to use the question type "Area"

Dear all, I donwloaded the Interviewer app with ESRI and created a question type “Area.” However, when I opened it, only a blank page appears when I click “Tap to edit area.” Are there other applications that I need to install or open while using this? Thank you.

Dear Lily,

This feature is experimental.
You can try it on demo server. Download interviewer app from demo.mysurvey.solutions (with unchecked checkbox). Also check on Diagnostics page that your version is with Maps.

or I need some details from you:

Which server you use?
Indicate your tablet model and its version.

Best regards,
