Upload Supporting Evidence:
multiple accounts of viewers and and witnesses. had someone run me through step by step to try to link steam in some way in order to work and could not.

This game does not support PC platform cross-play. MS store and Steam are treated seperately.
FS wrote they want to introduce cross-play “sometime after launch”.
From their FAQ:
Will crossplay and cross-save be available?
We see the value in cross-play and cross-save and fully intend to support cross-play shortly after launch. Cross-save is more complex to execute and still being investigated.

This is intended, at this time.
