Why can’t I name a nest site?

There are several things that can cause this issue:

1) You already have a nest site with that name. Try a different name.

2) Your session may have timed out and you need to update the app. Log out of the app (Menu → Log out) check for updates (apply if available). Relaunch the app and try again. See this FAQ about how to update your device.

3) Your device does not have the minimum required operating system to support the app. Android devices need an operating system of at least 6.0 and iOS devices need an operating system of at least 9.0.
