Purchased 4 new mini smart plug Kasa EP10 and none will connect to wifi.  I also tried turning off private address and limit ip address tracking in my phone settings and they still will not set up. Help or I will have to return and try another brand.  I have 3 other Kasa smart plugs, that are at least 2-4 years old and they are up and running and working with Alexa.  I have made sure the Kasa app is updated and it is on my phone.  Do you have other suggestions???
