LG C8 and Google Home Hub
We recently purchased the LG C8 and a Google Home Hub. Using the smart remote we can change channels/inputs using the Google Assistant. I created an account with the SmartThinQ app on an iPhone, logged in to the account on our TV under the "Setup for Google Assistant". (followed the online instructions https://www.lg.com/us/support/works-with-google-alexa-voice-assistant) With Google Assistant from our phones and the Home Hub we can turn the TV off and change the volume, but we cannot change the channel like we can from the remote.
In Google Assistant if we "Ask LG" to "show my devices" it says "None of your TV is connected to Google Assistant with LG. Please register your TV." I have double checked that our TV is logged in to our SmartThinQ account and that the account is linked in google assistant. Is there anything else I should check?
