Hnefatafl - Viking Chess Game

I went thru all your repetitive lessons first. Seems to be stuck displaying the same board position of the king once moved into lower right corner during lesson. Lessons are useless after that because same board position is always shown. No correlation of the board positions to the lessons. Tried your Branduhb 7x7 offline as Attackers first move. I moved from right edge middle up next to upper right corner. After that it locks up. Computer player as Defenders never moves. Also, AI analysis just spins doing nothing on iPhone version 16. By the way, the tafl rules are wrong anyhow. Wikipedia is wrong! (If Wikipedia hadn't automatically banned me for three+three years for pressing the time zone button twice for determining the first moment of Spring in 2023, and recently accidentally hitting an edit button near the scrollbar on iPhone, then the world might know the rules by now.) That 19x19 "Foteviken" is a sadistic joke.
