How to turn off autosave in KOBO

Hi everyone,
I am new on the forum and hope that I am posting in the right category. I have built the form in Kobo Toolbox. Responses will be collected online. However, questions are sensitive and I don't respondents to see that forms are auto saved because this may become for them obstacle for filling the form. I tried encrypting the form, but I get error message that local encryption is not supported. Is there any other way to disable autosave function so, that respondents do not get message that the saved form was retrieved? Any help will be appreciated.

Hi @Irina_Vardanashvili! This is a Kobo issue, so please ask at
