Multi platform play in EA

Greetings.
Was looking for answer on forums, but came out empty.

I've recently bought EA via PS5.
So my question is - is it possible to play on different platforms with single EA, or do I have to buy as many versions as there are platforms I would like to use?
Seems a bit too much for a game designed as cross-platform type.

I think it's blocked by Sony during Early Access (paid access), but will be unlocked after full release for the same account. Not 100% sure, you'll need an official statement for this.
