Material UI DatePicker Not Applying dd/MM/yyyy Format in React

I'm working on a React project and facing an issue with the Material UI DatePicker component. Despite setting the date format to "dd/MM/yyyy", the DatePicker displays dates in the "MM/DD/yyyy" format. CustomDatePicker Component:

import React from 'react';
import { DatePicker } from '@mui/x-date-pickers/DatePicker';
import { AdapterDateFns } from '@mui/x-date-pickers/AdapterDateFns';
import { LocalizationProvider } from '@mui/x-date-pickers';
import TextField from '@mui/material/TextField';
import esLocale from 'date-fns/locale/es';

const CustomDatePicker = ({ label, value, onChange }) => {
  return (
    <LocalizationProvider dateAdapter={AdapterDateFns} locale={esLocale}>
      <DatePicker
        label={label}
        value={value}
        onChange={onChange}
        inputFormat="dd/MM/yyyy"
        renderInput={(params) => <TextField {...params} />}
      />
    </LocalizationProvider>
  );
};

export default CustomDatePicker;

Usage of CustomDatePicker:

<FormControl variant="outlined" className="form-field">
  <CustomDatePicker
    label="Fecha de Nacimiento"
    value={fechaNacimiento}
    onChange={(newDate) => setFechaNacimiento(newDate)}
  />
</FormControl>

The issue is that the date format displayed in the DatePicker is not "dd/MM/yyyy" as expected according to the configuration. Instead, it's showing in "MM/DD/yyyy" format.

I've verified that fechaNacimiento is a valid Date object. I am also using date-fns with the Spanish locale.

Can anyone help me understand why the date format is not being applied as expected and how I can fix it?

I have tried setting the inputFormat property to "dd/MM/yyyy" in the DatePicker component, expecting the date to be displayed and selected in the day/month/year format. Here's what I have implemented:

Setting the Locale: I imported the Spanish locale from date-fns and used it in the LocalizationProvider to ensure that the date format and locale settings are correct.

Configuring the DatePicker: I configured the DatePicker with inputFormat="dd/MM/yyyy" to display the date in day/month/year format. However, the date still appears in the month/day/year format (MM/DD/yyyy).

Ensuring Correct Date Object: I verified that the value being passed to the DatePicker (fechaNacimiento) is a valid JavaScript Date object.

Despite these configurations, the date is still being displayed in the MM/DD/yyyy format instead of the expected dd/MM/yyyy format. I'm not sure if I'm missing something in the configuration or if there's an issue with how the DatePicker component handles the format.

Using these props, you can display any format text you want.

<DatePicker 
  localeText={{
    fieldDayPlaceholder: () => 'dd',
    fieldMonthPlaceholder: () => 'MM',
    fieldYearPlaceholder: () => 'yyyy',
  }}
/>

base on Mui document in this link you should add views prop base on your formt prop on DatePicker:

    //with [email protected]
    import { DatePicker } from "@mui/x-date-pickers/DatePicker";
    import { AdapterDateFns } from "@mui/x-date-pickers/AdapterDateFnsV3";
    import { LocalizationProvider } from "@mui/x-date-pickers";
    import TextField from "@mui/material/TextField";
    import { es } from "date-fns/locale/es";

    const CustomDatePicker = ({ label, value, onChange }) => {
      return (
        <div style={{ padding: 20 }}>
          <LocalizationProvider dateAdapter={AdapterDateFns} adapterLocale={es}>
            <DatePicker
             label={"label"}
             value={value}
             onChange={onChange}
             format="dd/mm/yyyy"
             views={["day", "month", "year"]}
             renderInput={(params) => <TextField {...params} />}
            />
          </LocalizationProvider>
        </div>
      );
    };

    export default CustomDatePicker;

Note: It will be different based on the version of the date-fns package:

// with date-fns v2.x
import { AdapterDateFns } from '@mui/x-date-pickers/AdapterDateFns';
// with date-fns v3.x
import { AdapterDateFns } from '@mui/x-date-pickers/AdapterDateFnsV3';
// with date-fns v2.x
import es from 'date-fns/locale/es';
// with date-fns v3.x
import { es } from 'date-fns/locale/es';

<LocalizationProvider dateAdapter={AdapterDateFns} adapterLocale={es}>
  {children}
</LocalizationProvider>;
