Red Bull, with Ferrari's behind-the-scenes backing, lodged three protests with the FIA about McLaren's flexible rear wing used in Baku. The FIA reportedly suggested to McLaren that a good way forward would be to make some voluntary adjustments to the design for future races, a solution the team accepted.

The FIA intervenes following intense scrutiny of McLaren's controversial rear wing design, which rival teams claim breaches aerodynamic regulations.

F1’s regulations limit the amount of flexibility permitted, but teams try to find ways to maximize this to improve performance.
