Solution
During the process of several weeks, I designed wireframes, mockups, tested and discussed solutions with the team. One of the improvements we made was new onboarding, where we explain the privacy rules to users and emphasize that recordings are set to non-public by default, meaning only the user can see them unless they choose to share them with the community. To make it easier to record the first response (statistics show that a significant number of users did not record any responses, whereas after recording the first response users usually record the next few, so we focused on this initial barrier of the first recording).
