Hi there. I had the same problem since last year. I somehow just resolved this problem now. I searched everywhere before on the internet and never found a solution. If you're still having this issue that you cannot link the LG ThinQ App to Google Home App or Google Nest Mini Smart Speaker and that your LG Smart TV is already linked to your LG ThinQ App and you can control it without a problem. Then 1st make sure your Google Assistant is setup on your TV and your LG Account is signed in on your TV. After that try these steps: 1- Turn on your TV and press the home button on your TV remote control. 2- Open LG ThinQ App and click on your TV tile. 3- Click the 3 dots in the top right corner and choose LG ThinQ TV Settings at the bottom of your phone's screen. 4- Tap on Location and assign your TV to a Room then tap save. 5- You'll be back automatically to the settings screen then right under Location tap Sign in to TV with your account, then you should see a confirmation on your TV and phones screen that you're logged in. 6- Back to LG ThinQ App settings as before and tap Set to use smart speaker if you have google home or google nest mini to control your TV with voice and then follow the setup steps on your phones screen. 7- Open Google Home App and tap the + sign on the top left corner and tap Set up device or whatever its shown to you, depending on your App version the UI might be different. 8- Tap Devices compatible with Google and search for LG ThinQ App and select it and follow the steps. 9- After that you won't see that error again and your LG ThinQ App will be successfully linked to your Google Home App. Go back to Google Home App and there you should see a tile named TV. 10- Open LG ThinQ App>tap the 3 burger lines on left top corner> Settings gear>Tap Voice Assistant>Google Assistant then follow the steps. 11- Hopefully DONE ✅. PS: if this didn't work you have to unlink LG ThinQ App from your Google account. To do so: 1- Open this website and login with your google account that you're using for Google Home App: https://myaccount.google.com/accountlinking 2- Unlink LG ThinQ App. 3- Repeat the steps all above. Good luck 🤞
