Child's account can't login

I have seen some threads about this and tried the things mentioned like restarting the Xbox and also removing there profile from the Xbox and then downloading it back onto the Xbox but none of these are working for me. I have an Xbox one that I have gold
on, I also have an Xbox 360 that my oldest son has gold on. My oldest son and I can sign in and play live on both Xbox's just fine. My youngest can sign on and play live on the 360 but not the one. I am stumped, I removed all profiles from the one and then
got them back on and nothing has changed. I appreciate any help.

:)

We have just realized that now he can play some games on live just not star wars battlefront on live

 

EA has their own age restriction so even if you as a parent are ok with your kids playing on games above their age EA does not allow this quoting this from another forum with same question "EA has always restricted online play of their games to accounts
aged 13 or older, even Burnout Paradise back on Xbox 360. It's not to do with game content, it's simply their policy on multiplayer.

Someone brought up Titanfall: it might simply be because EA only joined that project right at the end, and weren't the publisher from the very beginning, meaning Respawn had control over these things. Expect Titanfall 2 to conform better to the typical EA
policy" So sadly will have to play on a different profile to play Battlefront.
