Is that right.
So why has the FIA put a Seal on the device and has asked RB to remove it.

"....As first revealed by Motorsport.com,
concerns had been voiced by several teams that a device Red Bull had inside its car allowed settings to be changed to alter the height of its front bib under parc ferme conditions.
The FIA is clear that
there is no evidence Red Bull had ever made changes illegally, and the Milton Keynes-based squad is also adamant that it has always fully complied with the regulation..."
"..Sources have suggested that the revisions are not something that can be done immediately, because the adjustment device is in an intricate part of the car,
but it is hoped the changes will be ready for the race at Interlagos next month..."
The height adjustment device is nothing more than a screw-type system that can be twisted by a mechanic with a tool to raise and lower the height of the T-tray.
"..All teams have such a system,
although it is understood that Red Bull's is unique in it being accessible from inside the car - so it is hidden from view to outside observers..."
"..The outfit has also been open that it is not hiding anything,
especially because the design of its adjustment device has to be published on FIA servers as part of the open source element of the regulation..."
TLDR: some teams have complained, FIA have asked RedBull to change the design and remove access from the cockpit. Will happen in time for Brazilian GP.
