I've had my computer plugged in via this Tapo plug for many months now and it's always worked great. I've got my computer set up to automatically power on when it connects to power, so my computer turns on automatically when I have this smart plug turn on.

However, out of nowhere, the P100 has stopped turning off. If I use the app, my Google Home, or press the physical button on the P100, the Tapo unit turns on and off (which is verified both by the LED on the unit and in the app), but it doesn't power off the connected devices. Even when the plug says it's off, everything plugged into it stays powered on, it doesn't work at all any more.

It's running the latest firmware (or at least won't allow me to do any updates), and nothing has changed (in terms of where it's plugged in or what is plugged into it) in many months, the whole time of which it's has been working fine until the last couple of days.

Any thoughts?
