Earned cash back on qualifying purchases at participating brands will show up on your Ampli member account after your financial institution has posted the relevant transaction to your online banking profile. It may take up to 5 business days from the date a qualifying purchase is displayed on your online banking profile for cash back to appear on your Ampli member account.
Also keep in mind, if your cards/accounts are unlinked you will not earn cash back for eligible transactions. Simply re-link those cards and you'll see your cash back within your Ampli account. For accounts/cards with multi factor authentication, you may need to refresh that account/card within Ampli for you to see your cash back for eligible transactions.
