Sonoff Mini - Physical switching not working? [SOLVED]

Having some trouble with a Sonoff Mini. Running Tasmoda 12.4.0 and using the template from https://templates.blakadder.com/sonoff_mini.html (also ref attached template screenshot)

The ‘switch’ function doesn’t appear to work, however pressing the physical switch on the unit will toggle. Problem is, some of our house users are still wanting to use physical switch (S1 / S2).

Am I missing anything obvious?

So, the answer is yes… I was missing something. The template didn’t work via the GUI settings, however pasting in the template code did.
To do this, from the Tasmota GUI, click [Configuration] > [Configure Other] and paste in the following (from the blakadder link)

{"NAME":"Sonoff Mini","GPIO":[17,0,0,0,9,0,0,0,21,56,0,0,255],"FLAG":0,"BASE":1}

It should look something like the following (don’t forget to click ‘Save’

Hopefully this helps someone (like future, forgetful me)
