It appears that my HS 105 plugs are no longer able to be controlled by Alexa. Previously, I had no issues with controlling these plugs through Alexa, but now all three are unresponsive. I have tried disabling and re-enabling, as well as deleting and re-adding the plugs, but nothing seems to be working. Even the Kasa app, which has no problem turning the plugs on and off, is unable to get them to respond to Alexa. I have also followed the steps to enable the plugs on Alexa, and my internet and wireless connections are functioning properly. It is worth noting that these plugs have been working perfectly with Alexa for months prior to this issue. Any assistance in resolving this issue would be greatly appreciated.
 

Thank you.
