TPlink smart plugs Group Voice Commands not working in Alexa
I have several models of TP-Link Smart Plugs. Currently using EP10 and HS103. Previously I've set these up in a group of two Smart Plugs to turn TV on and a Remote Surround Sound speaker with connected Surround Sound Speakers, then use Alexa Commands to turn the TV and Remote Surround Sound speakers on or off. We just moved to a new home, and everything works except the Alexa commands to the group. The Alexa app and the Kasa app show up-to-date, but no version numbers that I can find.
The individual devices and groups are visible in the KASA app, and they switch correctly when using it. The problem is with the VOICE commands which do not switch the groups on or off. I have a 2nd TV in a bedroom, and it is designated as TV 2 which works with Alexa as a device and with Voice via Alexa. On our main TV in the Living Room, I've used group names of TV and Television, and the groups contain the two TP-Link devices named TV LG OLED and Surround Sound. The Alexa app does NOT show these Living Room devices while it shows the Bedroom TV 2 device. The apps are linked since the TV 2 works with voice or when switched using the KASA app. I've deleted the two Living Room devices and re-entered them, but the same problem exists. They are both shown as Living Room on the KASA app.
Suggestions? I must be doing something wrong but have not found the problem.
