Skype for businesss Sign in event received after a lot of delay after restart from sleep/ hibernate

Hello all,

Issue with my LyncClient is that I have observed a 2/ 3 minutes delay in getting event for SkypeForBusiness SignedIn after restart from sleep/ hibernate.

This issue is not observed on development machine but in customer environment.

I read somewhere that these events are received from SFB server and the delay can be because server takes time to sync the events with the client.

I am registering for the event using following code during app startup

Client.StateChanged += new EventHandler<ClientStateChangedEventArgs>(Client_StateChanged);

Any assistance will be helpful.
