Sorry if this has been asked and answered before but i have Smart plugs which work fine in the Kasa App, but will no longer work via Alexa.  Alexa identifys the plugs, and seems to link but i then get device unresponsive and am unable to voice control them which is the reason that i bought them.  These plugs were working fine until about 2 or 3 weeks ago and they just stopped.  I have removed them from both Alexa and Kasa, unplugged and replugged in. Kasa and then Alexa both re found them and all was fine, until i tried to control them via Alexa and then they switch to 'Skill unresponsive'  - so frustrating can anyone help please?   This is the only power i have over my childrens devices - mummy needs this to work!
