GE 45609 no long update status with manual operations

I saw an older post on similar issues, but I thought the problems were fixed back in September. But now I am having the same issues, all of my GE 45609 (on/off) switches, including both 2-way and 3-way switches, are no longer reporting their status after manually turned on or off, even though I can still control them with the smartthing app on my iphone (I will have to click the button twice to control them). Any suggestions?

Just to update my topic, actually my switches do report their status after manual operations, but just very slowly (2 or 3 minutes later after the manual operation). I have never thought it would take them that long so I have never waited long enough, but I thought these switches should report their status instantly.
