I have used a custom post type and ACF to build a bit of a site notification system for users. The only problem i have is if i want to do a site wide notice, because i need to add each user individually and it takes awhile. I have multiple selection on but still with over 1000 users its not an easy job..
I have an idea to fix the issue with adding another tick box and then running a special function, but i was wondering if there is anything already with ACF i am missing..
Just need to be able to add all users or all users of a certain role.. When i mean add i mean be able to select all users.
