We update bank data several times a day, but the frequency of updates varies bank to bank, depending on their technology infrastructure. With some, transactions will show up on the same day; with others, it might show up a day or two later. We try our best to make sure transactions show up on the same day, but with all the various banks we support, it's not always possible. If after adding a bank account and waiting a day, and you still don't see all your transactions, or they're consistently always behind, please contact us at [email protected] and we'll investigate further.
