Pimoroni Pico Plus 2 W: GPIO 16 defunct?

Just tried this on my Pico Plus 2W with just the LED connected and it flashes the LED.

import time
from machine import Pin
led = Pin(16,Pin.OUT)
for i in range(5):
    led.value(1) 
    time.sleep(0.3)
    led.value(0)
    time.sleep(0.3)

Have you got anything else connected, like a display?

This is the .uf2 I am using:

MicroPython feature/psram-and-wifi, pico_plus2_rp2350 v0.0.11 on 2024-11-26; Pimoroni Pico Plus 2 (PSRAM + LTE + WiFi) with RP2350
Type "help()" for more information.

See :
Pico 2w Network Module - Support - Pimoroni Buccaneers

The .uf2 does not include the W in its file name!
