I would believe that as long as the set box is numbered 2323110, that would clearly indicate that the set is the new "upgraded" Bluetooth 5.0 set. If the set box is numbered 6-84719, then it is probably the previous version that does not support "Voice Streaming & Recording (VSR)" feature using the LionChief App, this feature requires the Bluetooth 5.0 electronics to function. Lionel Voice Control is a feature of the LionChief App and should work with either version of the set. Of course, this logic depends upon whether or not Lionel actually changed the set box number, just in case Lionel didn't change the set box number, set box number is still 6-84719, my suggestion would be to try the "Voice Streaming & Recording (VSR)" using the latest version of the LionChief App to find out which version of Bluetooth the set contains.

Amazon is supposed to deliver my set today. I will update this post with the set number on the box after it arrives.
