It's been years... Cross platform save transfer?

I don’t play this game on my xbox. In fact, I stopped about 3 years ago now and have since sold it.
Is it still not possible to move my old stuff to the switch release? Because I’m still not starting from scratch.

As far as I know, only PC and Mobile versions are cross platform with each other. Not Xbox, Switch or Playstation.

Because of Microsoft’s, Sony’s and Nintendo’s requirements, each of these platforms is on a separate server. There’s nothing the devs can do about it.
