With the help of the post “How To Send Custom Persistent & Updateable Admin Notifications to Select Child Sites from MainWP Dashboard” (https://newcom.mainwp.com/t/how-to-send-custom-persistent-updateable-admin-notifications-to-select-child-sites-from-mainwp-dashboard/3940), we have posted a message for our customers in the dashboard of their websites. Now we would like to delete it completely again. What is the best way to do it with Code Snippets?
Thanks!
