Hi Julien,
I have prepared a quick example of creating a new Contact & Account.
The top most Form Configuration has been set to Contact, and the nested form set to Account. The Accounts' CRM Relationship has been set to 'account.primarycontactid -> contact.contactid', which will successfully create both records and associate the newly created Account record with the newly created Contact Record.
Additionally,
here is some documentation relating to the scenario that I based the aforementioned example off of.
Please let us know if you have any more questions.
Kind Regards,
Chris Rooney.
