Are you talking about the update of May 1st 2021? I'm always been skeptical about doing updates that only read Optimized Function Menu, because you never know when the gig is up for Autel as OE manufacturers contest their protected software architechture,and Autel either has to change something to it or remove it until a suitable work around is found that satisfies the court or they can sneak it back in a few updates later if enough people complain LOL.
