Xbox live EA account vs PC EA account

[uk_Revi]

Hey,

Please don’t kick off at me if this sounds dumb!

I just need to understand something about the EA accounts,

I have apex on Xbox and on PC, when I sign into my EA account for apex on the PC it signs me out on Xbox (I use the same credentials).

what I need to understand, can this effect the content I have on either game somehow? Or may it be effected when cross platform comes?

I’m guessing Apex/EA allow you to have multiple devices under one account?
