You can only share your games and apps from one headset though.
so you can turn on to make secondary accounts, yes, but only one headset is allowed to share.
so it’s meant to have one headset be yours and yours alone, and the other headset can be for the secondary users to share your games.
it sounds like you are trying to share your names on both... which would be nice, but it does not work like that.
BUT. Having secondary users and sharing games is still just a beta thing. Just in testing and trial mode. So they could very well revamp all of it in the near future
