Allow form respondents to save and continue to fill the form later

Another perfect example of Microsoft launching an underwhelming product to business customers and doing no further development on it.

Why not a simple option to save and resume? So easy to implement for 365 users who are signed in, partial responses tied with their account. But it seems no-one at MS considered this a useful feature to implement and need it to be pointed out by Joe Bloggs (over a year and a half ago in this case).

Keep up the good work guys!
