Ubisoft linked to Wildlands from xbox game pass, but if I buy game on steam?

Hello,

I have a save of Wildlands and my Ubisoft account is linked to Xbox Game pass, if I buy the game on Steam (ubisoft is also linked there as I have Breakpoint as well) - which save will take priority?

I don't really care about my save on xbox game pass as it's not very far into the game so I don't mind losing it.
