Hello there. You can manually refresh the bank feed and pull transactions, as your connection may have timed out.
If you're using the QuickBooks mobile app, tap Bank transactions > ellipsis icon (three dots aligned) > Updatebank transactions. Yet, if you're in a web version, go to Transactions > Bank transactions, then click the Refresh button.
If the issue persists, I suggest contacting your financial institution directly to check for any notifications that require your attention.
In the meantime, download the missing credit card transactions from the 20th of February up to the present time from your bank. Once you have the file, log in to your QuickBooks account via the web browser and manually upload bank data into the program. This process helps maintain accurate records and allows you to link your receipts once uploaded.
