I'm glad you've reached out to us. Let me help and share some insights about the bank feeds in QuickBooks Online (QBO).
The first thing to do is to confirm that these transactions are posted in your bank account since the transaction downloaded to QBO is dependent on the data provided by your bank's website.
Right after, you'll need to manually update your bank account to bring in the transactions to QBO. If in case you still can't see them in QBO, we'll need to download the missing bank transaction manually from your bank's website and import them into QuickBooks using WebConnect.
