I was just sent a link by a colleague to a google form. I can see that they ran a test of the form with "dummy' answers. Can the sender change this so that others don't see their responses in the form?
Maybe, it will depend on what kind of link the sender sent.
Google Forms has several kinds of links
- Submit a response
- Pre-filled response
- Edit response url
On case 1, the sender can't block collaborators to see the responses.
On cases 2 to 4, a form could be set to allow respondents to see previous submitted responses. The sender, assuming that they is the owner or a collaborator (editor), they could turn off this option.
