Never messed with family sharing before and I’m now exploring it. And it honestly seems a bit more complicated than I expected.
I no longer have a main PC. I now only play on the Deck. I don’t know if this information is important or not because it seems like you’re supposed to have a main device? Which I would assume is a PC.
My wife will be getting my original deck. I’m receiving my OLED tomorrow. And then my son is getting a PC his birthday, which is by the end of this month, where he can have access to my games too. It seems You have to authorize devices, and authorize accounts.

Will my OLED be my main device to authorize family sharing from? Do I have to be logged into every device? Can I not just share my library with my wife’s account that she will play on the original deck? Does this seem complicated at the moment because I don’t have the multiple devices in front of me?
