Admin notices manager is a WordPress plugin that allows you to better manage the admin notices in the WordPress dashboard so you read them at your own convenience and never miss an important message.
I noticed that the problem lays in the fact that we are always showing the notifications on multisite, and filtering does not work!
I have tried with both: super admin user, and a regular user, and all filters "only show for" and "hide for all except.." and in both cases, users could still see the admin notices.
