The whole windows/Linux thing would make a lot of sense if I was playing this or, literally anything on my windows desktop PC lately… But due to the convenience of portability, I’ve been playing exclusively on my Deck, so I’m not aware of any conflicts that should exist there.

BUT it’s entirely possible that I’m misunderstanding some of what you’re saying there, so please do elaborate if I’m just missing something -no attitude or negativity intended whatsoever. I’m not hyper familiar with the technicalities of their particular cloud save backup system.

It’s really frustrating that Valve has had this function for so long and still not have it working properly, even in cases where the game is only being played on one device. :(

Eh, don’t worry, you can fix that with some duct tape.
