Problems with Commonuser plugin to add a session

Hi,Everyone,
There was a problem when using the commonuser plugin: I would like to know if the login method of this plugin can log in to EOS? I used **TryToLoginForOnlinePlay(0)**This method, and ECommonUserPrivilege is also CanPlayOnline. However, I found that it was impossible to join the session. Yes, both the creation and search of the session were correct, but it was impossible to join the session.

The methods I searched for on the internet all involved using something like “IOnlineIdentityPtr Identity = Subsystem->GetIdentityInterface();” This method. Do I need to use this method to log in?

I will paste the log below. The log indicates that it seems I failed to log in to EOS successfully? It seems that it failed in the presence detection. What should I do to make it pass the check or do I need to disable the presence check?
