World sharing within one’s account

I feel like you should be able to access your Minecraft world from all of your devices that are signed in to your account. In other words if make a world on my phone, and I later swift to playing on play station, I should be able to go and play that world on my ps as long as I am on the same account. I really wouldn’t care if you guys put like a 99 cent fee on it to just for being able to do that, but either way it would be really nice not having to throw a file around different devices.
