OK so I think one of the questions that isn't clear.
If you merge/link to a platform, then log into another platform, do the items not available on that platform just become unavailable while on that platform? I thought the purpose of cross save was to allow me to, say, play on the PC, log out, grab my phone, then play there too, then log out, grab my switch, and play there as well.
Because, let's say a founder plays (I'm not one, sadge), and has a Skana Prime equipped. Then said founder gets a Switch, and tries to login there. Does he just not have access to that weapon and needs to grab another?
