Since your Press is connected to the internet, firmware updates will happen automatically.
In order for a firmware update to take place, your Press must be plugged in and connected to the internet. We release firmware updates over night to avoid disrupting your morning juice Press. If you unplug your Press at night, your firmware will download when you plug it back in. In this case, you may experience a short delay (3-5 minutes) while your firmware is updating before you can Press your Pack.
