I have several Smart Plugs and Smart Switches (2 way, 3 way & Dimmers). I recently installed a Deco M3 mesh system. Since then the Kasa App on my iPhones & iPads often lose connection with a Smart plug or switch. After clicking the on/off icon it just spins for a minute or 2 then stops - the plug/switch doesn't change. This may last for an while and then start working. Sometimes I have to delete the device and then re-install in the app. Weird thing is that Alexa can still control the device and often the widget works.
I have upgraded firmaware - deleted and reinstalled the app. Contacted support and given less than satisfactory answers 'reinstall or no-one else has this problem'.
I think that it has to do with the Deco mesh network - it only started to happen after the Deco got installed
Any suggestions would be helpful
