When does cashback start accruing in categories?

Cashback will accrue on purchases made after selecting categories, but not earlier than the first day of the month for which the categories are selected — the earlier you choose, the more cashback you can receive. For example, categories for December can be selected from November 27 to December 31. You can check the start date of the categories in the “Favorite categories” section. You can check the amount accrued in the “Transaction History” section.
