When you view a campaign, click on the 'Manage Sessions' section underneath the name of the campaign.
If you need to make any changes to a Peer Scheduling campaign, upload a new .CSV file with the updates or manually add to the table.
If duplicate sessions appear after uploading the updated .CSV file, check to see if there are any differences in the sessions between the pre-existing .CSV file and the newly uploaded one. The Elevate Platform interprets any differences (including single character changes) as a new session that will not override the old session.
