SearchResults.Num() value always 0.
can’t find SearchResults.Num() value

if (!SessionInterface.IsValid())
	{
		return;
	}

	FindSessionsCompleteDelegateHandle = SessionInterface->AddOnFindSessionsCompleteDelegate_Handle(FindSessionsCompleteDelegate);

	LastSessionSearch = MakeShareable(new FOnlineSessionSearch());

When you create the session, uses presence is enabled for them? Also, which engine version are you using? Recently a bUseLobbiesIfAvailable has been added to the FOnlineSessionSearch.

using UE5.
add in DefaultEngine.ini

bInitServerOnClient=true

Should I declare

LastSessionSearch->bUseLobbiesIfAvailable = true ?

Create Session Code

LastSessionSettings = MakeShareable(new FOnlineSessionSettings());
	LastSessionSettings->bIsLANMatch = IOnlineSubsystem::Get()->GetSubsystemName() == "NULL" ? true : false;
	LastSessionSettings->NumPublicConnections = NumPublicConnections;
	LastSessionSettings->bAllowJoinInProgress = true;
	LastSessionSettings->bAllowJoinViaPresence = true;
	LastSessionSettings->bShouldAdvertise = true;
	LastSessionSettings->bUsesPresence = true;
	LastSessionSettings->Set(FName("MatchType"), MatchType, EOnlineDataAdvertisementType::ViaOnlineServiceAndPing);

Yes, I’ve checked the source code and this param seems to take over the purpose of the presence setting.
