I have a Lenovo Smart Clock. Somehiw the display language is changed. I woul like to change it via the Google Home app, however when selecting the device > settings > display, it does not load the display settings (the google “loading circkle” continues to rotate). Factor reset of the clock and reinstall of the Google Home app did not help.
Thanks for reaching out to the Google Nest Community and sorry for the delayed response.
Please note that we have very limited support on third party speakers with built-in Google Assistant like Lenovo. Since you've done the basic steps and it still didn't work, it is best to reach out to them for better assistance.
Speaking on behalf of our Google Home speakers and displays, there's an option to change the screen display on photo frame settings. Visit this link to learn more.
While we love to help, we highly suggest contacting Lenovo support for assistance. If you have any new issues, updates or just a discussion topic about Google Nest devices, feel free to start a new thread in the community as I'll be locking this thread in 24 hours.
