Re: Can I change my ea account in apex on switch.

@Viuvve You are able to, however there a few things to keep in mind. I would recommend looking through our help article that will help you with this. 

• Unlink your platform account from your EA Account. 

There is a section for Apex Legends:

Do you play Apex?

If you unlink a platform account that you use to play Apex Legends, you may have issues with Battle Pass leveling, item unlocks, and other errors.

Instead of unlinking and relinking a platform account you play Apex on, it may be better to start fresh on a new account.
