"Keep your device plugged in and powered on overnight."
We are making changes to how software updates function on Square Register and Square Terminal to improve device performance and reliability. As a result, some software updates may now take longer than they do today.
We never want your business to be disrupted by a software update. To avoid disruptions, we recommend you keep your device plugged in and powered on overnight. Your device will check for and automatically install updates every night at 3am (or, change the time of automatic updates from 3am by going to Settings > Hardware > General > Nightly Reboot). Staying plugged in and powered on overnight keeps your device continuously updated and ready for use.
If you can’t stay plugged in and powered on overnight, we recommend periodically checking your device for updates, or budgeting time to install critical updates at the start of your day. Go to Settings > Hardware > General > About Register or About Terminal to check for updates.
