We sync transactions daily so that we can reward you the moment we see your transactions. However, depending on your financial institution, the process may take up to 4-5 business days. This is not a process within our control but rest assured that your reward will be allocated as soon as the data is received.
The most important aspect from your end is to ensure you ONLY use your sync account(s) and/or card(s) that you use regularly to pay for purchases. So sync as many account(s)/card(s) as you have.
