Dark souls 3 on Deck doesn't synchronize

[jejkoojej ツ]

Can any one tell me how to synch my saves from a laptop to steam deck? I've bought deck to play DS3 in the first place and now I can't make this bloody thing to download old saves from the cloud.
I've spent most of the day trying different things like running the game on the laptop and then on the deck, creating new character on the computer and then on the deck so on and so forth... every time this ♥♥♥♥♥♥♥♥ game starts it says (both on laptop and on deck) that it is checking the status of synchronisation or something like that and nothing ever happen.
At some point it was saying that if I will start the game on the deck it might cause problems witch synchronising since there is some data in the cloud that haven't been downloaded on to the deck but waiting and closing and running the game again wouldn't do anything ><
It's just so infuriating ><
Any ideas would be much appreciated:/

DS3 doesn't have cloud save. You have a save file that has on it all your save data. I don't have a deck but I imagine you would have to install Windows on it and download your saves from an upload or something, so unless this can be done on the Steam Deck OS, you likely have to start anew.

I just don't understand then why does it check for synchronisation before starting:/
In any case thank you for your reply:)

In the end I gave up on synching and went with manual copying save files it was hard for a dummy like me but it was worth it since at least now I can go forward instead of starting all over again:)
