If one ever needed a blatant hint that the mandatory tutorial might confuse users in its current form. Have a look at yesterdays LTT Anthony Joung review of the pinephone.
He obviously does not even realize he is in a tutorial (possibly being distracted by video production itself) and dismisses further testing all over
I cannot think of a more obvious hint then to display “TUTORIAL” or alike in the background during active tutorial. But most likely there are better ways.
Maybe this would even make it redundant to offer a “end tutorial” option.
But just from watching the video Anthony could have been helped if there was an option to end the tutorial as well as making it more obvious to him.
