Thank you for bringing up the concern you're experiencing, I would love to look into this further for you. The first troubleshooting step that I'd recommend would be to restart your device. This process should keep all your settings, and reconnect it to the same Wi-Fi network. This is helpful if it ever freezes, has connection problems, or isn't working normally.

Aside from restarting your Nest Camera, you may try giving these steps a try:
Let us know how it goes.
I appreciate the help, Brad.
