When you first create a bank-connected account in Wallet, your entire transaction history will not be downloaded. Wallet should download your bank transactions for the past 90-180 days (depending on the individual bank's policies).
If you connect your previously bank-connected account in Wallet again, your transactions will still be downloaded, but only up to the most recent transaction previously taken from your bank.
FAQ
How to get more transactions?
You could try adding older transaction by using our Import feature on the Web App.
Can i start without importing any records?
No, transactions from the last 90 or 180 days are added, but this depends on the bank's settings, it depends on what information they want to share with third parties.
