First, go to the Jobs page by clicking on the Jobs link in the left menu bar.
Then, click on the “View recurring activities” link near the top right of that page.
This will show you a list of all recurring jobs. Click on the blue “Edit” button next to the job that you’d like to cancel.
Proceed to set the “End Date” to today’s date. (if you don’t see the End Date field, you’d need to enable the “Show more” mode first.)
After you click on the “Save” button, all future occurrences of this recurring job will be automatically removed from your calendar.
