If you would like the Countdown Timer Bar to be displayed for only a certain amount of time, you can use the "Disappear After" option.
How "Disappear After" works:
This feature will make the bar disappear after a set amount of time. So if you set it to 60 seconds, then the bar will disappear 60 seconds after initially loading.
This feature can be used along with "Delay Before Repeating" to ensure that the bar does not appear frequently. Please click here for additional details.
