Definitely not fixed. I've reconnected, disconnected and connected
again. Switched between Gosund and Tuya and back again. Still Google
Home stubbornly refuses to acknowledge that these are 2 gang switches.
Alexa gets it, Google not so much.
Well I now have the same issue. Many devices and one by one they are
'breaking'. They disappear from the app and then when they reappear they
are single switches. I'm using gosund rather than tuya. To be clear,
Alexa still recognises these as 2 gang ...
