Firmware 2101 on my QN94A 2021 QLED has broken Dolby Atmos on the internal Netfilx app, it did also break Atmos on all other apps and inputs but have manged get Atmos back with a series of resets and replugs expect for Netflix which still shows 5.1 using a HW-Q700A soundbar with firmware 1010.1.
EDIT: From the various model numbers reported it appears that this issue affects the T-NKM2DEUC platform in general.
A user on a another forum suggested re-pairing the solar remote to the TV to get the battery level back which has worked for me. You can re-pair the solar remote to the TV by holding down the backup and play/pause buttons on the remote until the TV reports that the pairing is successful.
