Dolby Atmos not working on HBO Max??

It seems that Dolby Atmos is not working on Max. I have two separate sonos systems, one Ark in the living room connected to LG C3 and one Beam in the master bedroom connected to LG C2.

HBO max is not working with Atmos with either systems, also tried using an Apple TV and nothing. Dolby Digital Plus 5.1 is what I get.

Atoms works fine with the Disney app and the LG built in Apple TV app on both sonos systems, as well as my Apple TV device.

Was trying to watch the new Kong movie on HBO Max.

Can someone confirm if Dolby Atmos is working on the HBO app, on either an LG TV or Apple TV device?
