Earlier this evening I was doing a review of my Google Security settings, and saw a couple old phones and computers in the list, so for good measure I signed out of my devices that were using my Google Account for logging into various apps and started relogging in on my current devices, however I noticed a notification for a email that I had deleted my Nest devices. I did not delete them I only signed out as part of good security practice on my network. I logged into the Nest app using my Google account credentials, and I got a choice to select my Home's Nickname or to create a new home. I selected the one that had always been setup and was asked to put my address in again have which I did, but the next screen asked me to set up my Nest Subscription again, it said said I didn't have a current subscription.
This is super frustrating, I have a Google Nest Hub Max in every room of the house, at least 4 Nest Cam Indoor, a full suite of Nest Protect products. I am concerned that my historical cam footage may have been deleted, i try to back it up in Google Takeout but it never seems to work, the export always crashes (suggestion Google: Give us an option to select a specific camera in Google Takeout, it would be much smaller of a file).
This is too long already, so Google or a community member hopefully someone knows how restore the devices back into my Nest app, since I only signed out of my devices, there has to be a way to sign back in to restore the devices back to my account/app along with all the device settings?
I apologize for my late response and thank you for all of your patience while waiting for a reply. I understand how frustrating your situation must be, and I hope we can find a solution together. Do you still need help with this issue?
Restarting and factory resetting your Google Nest camera or doorbell will have different results:
Restart: Keeps all your settings, and it should reconnect to the same Wi-Fi network. This is helpful if it ever becomes frozen, has trouble reconnecting to the internet, or isn't working normally.
Factory reset: Erases all your settings and options, and restores its factory default settings. It will not automatically reconnect to Wi-Fi and you'll need to set it up again.
