Hi I have requested to connected my nationwide credit card with transactions going back to December 2029. The account connected but only the last trans action is showing

Hello there, userduncan.

The first time you connect your bank to the system lets you download the last 90 days of transactions. Others can go back as far as 24 months. If your bank is unable to download the past transactions you wanted, you'll want to manually import them into QuickBooks Online. You can follow the detailed steps on this reference: Manually upload transactions into QuickBooks Online.

Here are a few articles that you might need for future reference:

Let me know if you have other questions. Take care!
