Unfortunately this is not as easy as it might seem to us. While we only pay one store front (be it Sony Marketplace, Steam, or the EA App) other platforms require a 'cut' of the profits from all sales through their respective platforms. Due to the nature of Steam still requiring the EA App running also, this is already possible for content to transfer. However, for console to console or console to PC transfers, that would require re-negotiation of the entire deals with Sony, Microsoft, and Nintendo so that they still get their cut of the profits for what is essentially them having to give you games for free. Nintendo especially is very notorious for a hard "We do not cooperate" stance with other games. For example, a popular Battle Royale game does not allow currency purchased on Nintendo Switch to be used on other platforms. No other platform has this restriction, and the reason that the game has no Nintendo licensed content is also because Nintendo strangely insists that not only any Nintendo characters added to the game only be usable on their platform, but also that you can't even see their characters on other platforms... something the makers of the game obviously can't or are not willing to do.
