Thanks everyone for your update, for some reason I had thought Beoremote One BT will work with Sony the same way as LG.
In any case, I have paired with my Apple TV using BT for now – only issue is when changing products to another BT connection such as Beoplay A9, I have to reconnect the Apple TV again by going into the Apple TV bluetooth menu, any way of reconnecting the remote to Apple TV without doing that?
