It seems like the Free analysis behaves differently than the paid full AI analysis aside from the limit of highlighting and showing moves for only three moves. The buttons used to highlight the moves behave differently. It trips me up each time I use the free one to look at a game I observed.
In the free version it shows the move before what looks to be a mistake by the opponent. For example if black makes a mistake the button will show the white move just before that. The full AI review seems to do the opposite. The button shows the black error.
Am I understanding this correctly? Also, any idea why they are different in this way?
