Game save multiplayer

My friend and I have a save but we can’t always play at the same time. is there any possibility to transmit the save?
My friend sent me his save but game selects his village for me, I can’t play on my village.
can someone help me?
Maybe a way that automatically saves saving on both computers without the problem of playing with the wrong village

Or you both have some overlap in playtimes allowing each other to update your own worldsave with
