Hi, thanks for your support ticket.
In the meantime we also had contact via our support channel to discuss this subject, so I will add a summary of that over here and then close this ticket. Please contact us via our support channel if you have more questions on this subject.

The request was to limit each logged-in WordPress user to be able to submit a form one time, to prevent one user filling out the same form multiple times. Such a filter is not possible upfront, so 100% preventing this is not possible at the moment.
A suggested workaround is to collect certain WP variables within each submission, so you can filter on duplicate entries afterwards. More information about using WP variables can be found over here: https://tripetto.com/help/articles/how-to-use-wordpress-variables-in-your-form/
Another possible workaround would be to develop something outside of Tripetto that checks the value of a WP variable to the submissions (as all submitted data is stored inside your own WP database). And if you find a match, then not show the form at all. This is a workaround that’s outside of Tripetto and needs custom coding at your own end.
