Keeping your MainWP Dashboard site up to date is as important as keeping your child sites updated. Since the MainWP user interface hides the native WordPress sections, the warning icon/button in the header element will notify you when there is any update available on your WordPress site (including Plugins, Themes, and WP Core) where you have the MainWP Dashboard plugin installed.
Click on the icon to go to the WP > Updates (/wp-admin/update-core.php) page, where you can easily manage the available updates.
