Sorry to comment again. Realised my problem before was that the Templater app hadn’t been updated.
My issue now is that when I use alt + N to create a new note, I then have to click the correct template (I only have one). Perhaps too much of an ask - but is there no hot-key / shortcut to just create new, with the template in one click or shortcut? Given that I create a new note every few mins with the same template, this would be very useful.
