If you (temporarily) want to prevent screenshots being taken, but keep access to your screenshots, you may pause your URL.
You can pause or resume URLs from the main page - in Grid view or List view - by toggling the play/pause icon in front of the scheduled screenshot date/time. If a play icon is shown, you can click that to pause it. If a pause icon is shown, you can resume it.
A paused URL is also indicated with a gray and italic date/time.
In List view, you can also pause or resume multiple URLs at once:
To resume multiple URLs, do the same as above but select "Resume" in the second drop-down.
If you want to resume a URL with a date in the past, it will capture a new screenshot right away and return to the previously set screenshot frequency.
A paused URL has a schedule frequency to be captured every day at 12:00, but it has been 3 months since the last capture and so the old "Next screenshot" time is also 3 months in the past. If you resume the URL, it will capture a new screenshot right away, and it will set the new "Next screenshot" time to 12:00 the next day (or this day if it's still before 12:00 o'clock in your set timezone).
