I had a 2018 Audi A8L and was able to operate the rear sunshade while the car was moving. I could raise or lower it at any speed at anytime. It worked great and I really liked it. I just bought a 2021 Audi A8L and find that I can not operate it while in motion. Once I hit 15 mph the button grays out the MMI task bar and can’t use it until I slow to under 15. The dealership service technician said it’s supposed to be like that way for safety. If that’s true I think its ridiculous. Having to stop the car to use a sunscreen is more dangerous than just using it while driving. My thought is that it’s a MMI program error that needs to be corrected. Does anyone else have this issue?
