Hello,
When I run the client version of GetSharedGroupData with a SharedGroupId, the data returns fine but when I do the same thing with the Server version, it errors out saying invalid SharedGroupId. I have tried two different SharedGroupId, confirmed that they exist using the Shared Group Data interface in playfab. I am not sure what I am doing wrong with calling the server version or if there is a bug with Server.GetSharedGroupData in playfab.
"SharedGroupId": "B34221CC549CF8C3:Gifts"
