When i try to set up the nest, after the main setup is cannot conclude it. Immediately it is shown in the home app at deviced as OFFLINE but i can control the sound. Its very weird. Then it can take requests eg weather and on/off devices but everyday asks me to log in to the google home app. Next day connection gets lost and the smart speaker asks me to log in again.
Tried 2 different androids. With different emails, all the tries after factory reset . It seems the factory reset isnt fixing the issue.
Thanks for reaching out.
When did it start happening? What Google Nest device are you referring to? Also, are you using a private network? If so, do you have a dual-band router?
Additional questions: can you check your Google Home App feed history to check if there is any recorded activity of your device being unlinked from the Google Home app. Do you have experienced Wi-Fi issues in your home to rule out a Wi-Fi problem? Also, how frequently does your device unlink (daily, weekly, etc.)
