in the pause menu, which is in the top right, while you're in adventure mode
Oh I didn't realize that since in the main menu settings where I first looked there was no such option.
this likely means that a tutorial was waiting for you to do an action that it considered meant that you understood the tutorial (end turn tutorial: end your turn, draw a card tutorial: draw a card, etc.) but some condition or another prevented that from happening
I see, I just did another run and that worked, I didn't realize that doing the action would ensure the tutorial didn't pop up, before I was just using the arrow to hide the tutorial each time it came up.
