What's going on with Lambiase after McLaren-Red Bull disagreement?

Max Verstappen's race engineer Gianpiero Lambiase will join McLaren in a surprise move by 2028 but there appears to be a difference of opinion about the role he will hold.

Red Bull announced last month that Lambiase was leaving his role as head of race engineering and Verstappen's engineer to join McLaren, who said he would take up the position of chief racing officer "no later than 2028".
