Mea culpa time.
i didn’t follow the instructions, which I only found in the video.
Brina, the templates do save, but they aren’t nested in any folder on the left. You can see them when you create a note, where you’ll be given an option to pick one of the saved templates.
My fault for not following directions, although it would be great to view all the templates in a folder (and if you can do that, my apologies again).
Hopefully this follow up can help someone else who made the mistake I did.
