谷歌游戏回合制邀请被错误地识别为INVITATION_TYPE_REAL_TIME

Question

从设备A，我向设备B发送基于回合制的邀请。但设备B虽然收到邀请，却错误地将其识别为实时邀请！显然这是一个问题，我无法继续游戏！

我正在发送设备A的邀请，如下所示：

TurnBasedMatchConfig.Builder matchBuilder = TurnBasedMatchConfig.builder();

int minP = 1;
int maxP = 1;
int bitMask = 0;
int variant = -1;
ArrayList<String> invitees = ....list of players here...

if (minP > 0 && maxP > 0)
{
    matchBuilder.setAutoMatchCriteria(RoomConfig.createAutoMatchCriteria(
                        minP,
                        maxP,
                        bitMask));
}

matchBuilder.setVariant(variant);

if (invitees.size() > 0) matchBuilder.addInvitedPlayers(invitees);

Games.TurnBasedMultiplayer.createMatch(_client, matchBuilder.build()).setResultCallback(new InitiateMatchResultClass());

在设备B上，我收到了这样的邀请：https://developers.google.com/android/reference/com/google/android/gms/games/multiplayer/OnInvitationReceivedListener

@Override
public void onInvitationReceived(Invitation invitation)
{
    Log.i(ExConsts.TAG, "onInvitationReceived");

    if(invitation.getInvitationType() == Invitation.INVITATION_TYPE_REAL_TIME)
        {
            Log.i(ExConsts.TAG, "INVITATION_TYPE_REAL_TIME");
        }
        else if(invitation.getInvitationType() == Invitation.INVITATION_TYPE_TURN_BASED)
        {
            Log.i(ExConsts.TAG, "INVITATION_TYPE_TURN_BASED");
        }
}

我可能做错了什么？！
