Today is April 23rd. I also have the same issue going on since April 16th. Error code 4009. My  main bank has not uploaded. This is very frustrating. I have tried everything to reconnect. Nothing works. Appears qbo does not recognize the bank. By the way, this is TD bank.  Called help desk this morning. No time frame for the fix is available. Told the engineers have the problem but have a very heavy case load. I understand everyone is very busy but this is people' businesses. No excuse. Only work around, if it works, is to manually enter the transactions. That' alot of transaction in a weeks time and alot of extra work on my end. Quickbooks has the market cornered and needs to fix these issues in a timely manner.
