I don't use a smartphone, but a Personal Computer with Windows 10 Family, 64 bit. I only ever used Steam to buy and install the game. and didn't use itch at all.
Oh, weird you’re on itch then for support, the steam page has a discussion page with support there!
On steam you can just let the game update automatically, it will remember everything, no intervention needed. Just play the game!
Oh, great, thanks you very much for your answer.
Sorry for the confusion.
