The bank balance is correct but transaction are not appearing for me to review. I have updated several times. My last transaction I was able to code was form 11/9/2018.
Login to your bank and identify the transactions that have not come through the bank feed, if they are more than 3 business days old, follow up with your bank if your connection to QBO does not need to be updated. I would first disconnect and reconnect your bank account to QBO, this does need to be done at times.
