Radar Beep can't be turned of anymore since 2.1.1 on Seal AWD

Hi guys, so there is a button on the AVM that turns off the radar beep, while the visual radar feedback is still functional. It's left from the 3D button. Perfect to park in narrow spaces while the kids are asleep. Since 2.1.1 this is broken. It also seems that the button icon changed, but I can't remember how it looked like before. Anyone else having this issue? If It is working for you, should I factory reset the car or something like that? In now over two years with this car it is the first time for me having a negative thing after an update.
