Ea acsess

You could try to download the EA Access app that located in the store and once you download that, check out the games inside to start the downloads.

The Ea Access should only be available for the person who has the subscription, so I don't think you can simply game share it.

How do i use my ea acsess that someone game shere with me

Hello,

The Play First Trials can only be played by the main account, However if you're talking about the Vault games, these can be shared between accounts just like any owned games.
Make sure that the account that has the sub is logged in or has that console as its home account and you should be good.

What error do you get exactly? You can use the link provided by XBF George too. That should work fine.

As long as the account that has the subscription is set up as the home console on your end the vault games should work as all other games you share. Only the time trials won't work to share.
