Multi view drops dolby atmos

[ChuckEllis]

When I try to smart view dolby atmos content from my tab s10 to my s90c tv - samsung to  samsung - the TV goes into multiview and the sound output switches from the AVR to just the TV speaker. If I change multiview to None, single screen, the sound switches back to AVR with full dolby. How can I get dolby AVR to work in muktiview
