Deactivating a pop-up
If you want to deactivate an old pop-up, go to the left-side menu, click on the On Site button, and scroll down to Dynamic Pop-Ups.
Next, select from your list the Pop-up you want to pause by clicking on it.
This will take you to the active pop-up.
Under the title of the pop-up, slide the button to the left and pause it.
Don't forget to save the changes!
