Shows always OFF for Kasa Smart 3 Way Switch HS210 KIT

I changed 3 way switch in one of the location to Kasa HS210. Some how app always shows the switch is off all the time. when I try to turn on it turns on the light and on HA dashboard it shows green for few seconds and changes to show like it is off though it is on. Let me know if anyone has this issue and any fix.
