I have a Kasa switches and dimmers all over my house. There is one box with 3 switches. 2 of which randomly stopped working. The green wifi light flashes along with the white circle light. Both don't connect to the app. All other switches including the one next to it work fine.

Wifi has been reset 3 times. Both switches Haven been reset by holding the reset button for 15 seconds. Same thing, keeps flashing. If I manually turn the lighta on it flickers at the same frequency as the blinking.  Please help.
