Hi @yaroslavpaz!

It appears that you have still not enabled the Unique Submission setting. To prevent multiple submissions on your form from mobile users, please follow this guide: How-to-Set-Unique-Submissions-on-a-Form and select the Check cookies and IP setting. If you are expecting your users to fill out the form multiple times, then I can suggest going through the process of creating a unique code for each respondent which will be checked before a respondent is able to submit again. You can follow this guide for more information: How-to-Have-Unique-Question-Using-Multiple-Fields and let us know if you have any questions.
