TP-Link Kasa HS300 Master Switch Compatibility Issue

Hello everyone, I just wanted to share my experience with the TP-Link Kasa HS300 Master Switch and see if anyone has encountered a similar issue or can offer some advice. I recently connected my HS300 6 Outlet Power Switch, which includes six outlet devices and a master device in Home Assistant. However, I’ve noticed that when I toggle the Master switch, it only affects Plug 1, and the other plugs don’t respond. This is a bit frustrating because I was hoping to control all six plugs simultaneously with the Master switch. I’ve checked both the Kasa app and the Home Assistant device/entity settings, but I can’t seem to find a configuration that allows the Master to control all six outlets. Has anyone else experienced this issue? I’d greatly appreciate any tips or insights on how to resolve this. Thanks in advance for your help!
