Seeing the same since the update yesterday Matias.  Looks like res.partner is opening in a different view.  Will hopefully get chance to take a look this week.

Hi,

In Odoo POS, when you click Create New Customer, the system normally opens the res.partner form inside a popup, allowing you to enter all customer details. If instead you are seeing an “Edit Partner” simplified screen, it usually means that POS is falling back to a restricted quick-create view rather than the full customer form. This can happen if a module has overridden the default POS customer popup (CustomerEdit), or if there is a mismatch in the context being passed when creating a customer.

To investigate, you should enable Developer Mode, then try creating a customer in POS and check which view is being loaded. You can also look in Settings → Technical → Views for any partner views related to POS, especially ones recently added or modified by custom modules. If you recently installed or updated a POS-related module, that is the most likely source of the change.

The issue can be fixed in two main ways. One option is to adjust the POS CustomerEdit component in JavaScript so that it creates customers with the full set of fields instead of the restricted version. The other option is to disable or replace any custom res.partner view linked to POS, so that the system reverts to the standard customer form. Both approaches will restore the ability to create customers with all the usual fields directly from POS.

Hope it helps

Thank you for your response Rani. We haven't done any updates or customization, and I have also checked the permission settings and nothing works.
