I got an email from # saying my router has an issue and can be replaced for free.
About the same time, I noticed that my router reboots every 15 to 20 minutes
It is great that Google noticed this issue and tried to fix it, but the problem is the link to "this form" doesn't work, it only opens the nest support homepage. so I cannot request the replacement.
Could you tell us the case ID provided in the email? Also, when and where did you purchase the device? We'd be happy to take a look into this for you. Please fill out this form with all the needed information then let me know once done.
