Currently, retrieving a Friends list via GetFriendsList() returns Master Player IDs.
In order to use Lobby.SendInvite(), it requires a Title Player ID. This causes extra work and hassle on the client side as you have to make extra calls to translate between.
- Option 1: Add or change the SendInvite call to allow Master Player IDs. That way, no conversions or extra calls are needed on the client.
- Option 2: Update the FriendInfo class returned from GetFriendsList() to include both entities (Master and player) or both string IDs.
