TP link switch connected and working but other lights in house don't turn on
I purchased the TP link switch for my apartment and got it installed correctly, however none of the other lights (that have the dumb switch) in that section of my house will turn for some unknown reason. The orginal dumb switch was connected with 3 and there was a white ground wire in the back. I know i've wired everything correctly as the light turns on and works but I have not the faintest clue why the other lights don't work. I've searched the entire web and no good answers have come up. Any help would be amazing!
