Hey google suddenly not working correctly

[Tibbs1cat]

So I've 15 light devices in my lounge, 2 Govee, several Meross, and others linked through various Apps like Tuya, Magic home, Govee, Smart Life, suddenly 'hey google turn on/off lounge lights' only works with 2 devices! However ask Google to dim or change the colour of the lounge lights etc and they all work fine, or ask Google to turn on the individual device like the fireplace light and it works fine again, If I move said device and tell it's in the kitchen for example it work fine, put it back into the lounge and it won't turn on or off again so it's definitely a Google fault just with the Lounge! But why and why all literally overnight!? Anyone know a fix other than to reset all my devices?

Have you reconnected the relevant apps to Google Home in Works with Google?

Yeah done all that, it's a Google fault without a doubt, I removed the 'lounge' completely then set it all back up and still wouldn't work, re named it to just 'room' and it works perfectly, Google just doesn't like the word lounge!
