A small Apple TV system update is available tonight. This is tvOS 16.3.3 which brings only one new feature: the correction of a bug causing instability in the connection of the Siri Remote with the third generation Apple TV 4K. This bug only affects the very latest model of Apple TV released last October, tvOS 16.3.3 should not be offered on older models.
To install tvOS 16.3.3 on the third-generation Apple TV 4K, you can trigger the manual installation of this new version in the Settings app > System > Software Updates > Update Software.
