If a guest has earned points on a date after a campaign has ended, always check your receipt age setting in dashboard. Post Check-in Campaigns allow for guests to earn on receipts that occurred during the duration of the campaign. However, your receipt age setting determines how long the receipt will be valid.
Example: If you run a campaign of "double points" for one day only (15th of the month), and the receipt age setting for you business is "3 days"; guests will only earn double points for purchases made on the 15th. However, they may be gifted the 2X points any time from the 15th-18th when they scan the receipt that was created on the 15th.
Note: If you do not have access to view your receipt age setting, please contact your Customer Success Manager and they will verify it for you
