So I installed MBUX 2.6.1 OTA. And luckily mine installed and showed up with MBUX Sound Drive(FYI if yours is not working, check digital extra - infotainment tab in you mercedes me connect app), BUT now Dolby atmos surround sound is gone(started working after MBUX2.4 OTA).
In MBUX2.4 there is a Dolby Atmos toggle when you go to the setting on Audio Tab, and Online music, and under Apple Music there will be a toggle, and when playing Dolby Atmos content a Dolby Atmos logo shows up on the playing page(expanded if zero layer). Now both are gone. Supposedly 2.6.1 added support for amazon music Dolby atmos, but i added a amazon music account, nothing shows up for that either.
Car is a 2023 C300 4Matic(with 3d Burmester package).

Asked dealer about it, they said nothing they can do, tell me to talk to MB customer support. Talked to MB customer support, they said bring the car to a dealer.

Am I the only one running into this post update?

Thanks,
