I cannot re connect 2 p100 tapo plugs. I have already re connected 2,  but the other 2 just won't connect. I have tried everything.  Reset, re installed, checked wifi, (2.4gz and 5gz), turned Bluetooth on off, used 2 different handsets and even had 6 emails back and forth with tp link. No joy. Ive set up 10 cameras, 12 different lights, (inc L930 strip lights), video doorbell,  robot vacuums and 2 other p100 plugs amoings other tapo tech but these 2 are not re installing.  Tp link are wasting my time so what am I missing? (And I know it's throwing them in the bin and not recommending p100 to anyone is the correct answer 🙄).. 

Thanks
