I'm trying to add friends from the client using AddFriendRequest, and passing in the Display Name as the 'request.TitleDisplayName', and even though I am using the correct capitalism and letters, it always tells me "User not found".
I thought to instead use a GetAccountInfo request, and pass in the TitleDisplayName with the friend ID, then use the PlayFabId in that response, but it also returns "User not found".
