Hi Jorge. The best way to handle this will be to enable logging on your site. You can enable logging by going to Forms > Settings > Logging. Select: On, then [Save Settings]. By default this will enable all logging on your site. Documentation for Enabling Logging: https://docs.gravityforms.com/logging-and-debugging/#enabling-logging
After enabling logging, please test the form.
After testing the form, please open a support ticket here:
