PC VR Link not available on child's account

Hi

I've successfully connected the headset to Meta Quest Link software on my PC via Air Link when using my account.  When using my child's account, it won't allow them to enable PC VR, saying they need to speak to their parent.

I'd seen some guidance online that I need to be logged into the PC app which I am.  The child's account should be able to still link to the PC using their account on the headset and the appropriate restrictions would be applied according what I have set for them.  However, I cannot enable the PC VR option within the headset.

Any help would be appreciated.

Thanks
