I want all (!) data that I create on my PC at the same time on the laptop and vice versa.
At the moment there are two different devices. But couldn't you merge them? "That means everything is the same, nothing is different. And if I change something on one device, it should be synchronized live on the other.
Is that possible?
I'm sorry for being so stupid here, but I don't know how to put it another way.
