I can download the app and sign in, but why can’t I see any of my existing nest sites?
First, check that you are logged in with the correct username and password. Some people have more than one account and accidentally sign in to the wrong one. Use “forgot username” on the login page to get an email with your usernames. Note that you may need to do this multiple times if you have more than one email address associated with a Cornell Lab account, and remember that all Cornell Lab projects and websites (e.g., eBird, Project FeederWatch, Birds of the World, Bird Academy, etc.) share the same login system.
If you are signed in correctly, then your phone or tablet may not have the minimal operating system required for the app to work properly. View the current software requirements for Android and iOS devices.
