Silver is locked to the platform you buy it on.
Hello. Silver does not transfer with Cross Save — it's bound to the platform it's purchased on. [quote]Q: Do my previous game purchases transfer across platforms? A: No. The things you have purchased from your PC or Console stores will remain on the platforms where you bought them. These includes games or balances of Silver. Cross Save enables you to access the Guardians and Collections on one Active Account from wherever you play. The things that you acquire for your characters in the game are what move with you from one platform to another.[/quote]
