We decided to modify our settings in Luminate Online so a recurring gift will be cancelled after a certain amount of failed charges.
When do the updated settings go into effect? How would they affect our donors with failures on their sustaining gifts already?
The settings take effect on the next charge of the sustaining gift. At that time Luminate Online evaluates if a donor meets the criteria of the settings.
So if you had changed the setting to '3' and a recurring donor already had three failures then at the time of their next charge (their fourth charge) their gift would be cancelled. It would not have to fail an additional three times before it cancelled.
