I currently use QB Premier Professional Services Edition 2018 and have been successfully downloading Amex transactions for many years (have been a QB customer for 18 years), but now I am receiving an OL304 error saying "Your bank doesn't recognize this account number. Make sure that the account number, account type, and routing number are correct in the account list..." Nothing was changed in QB, and I'm still able to successfully log directly into my Amex account directly using the same ID and password, and I verified nothing was inadvertently changed in the "Bank Feeds" info in QB. I even tried rebooting and waiting another day in case there was something going on with either company, but still the problem persists. This is probably totally unrelated, but I'm also having terrible problems with QB locking up repeatedly while trying to edit Employee information or exiting unexpectedly while editing an Invoice, and I'm wondering if I may be reaching some QB file size limitations. For as long as this product has been in existence, all of these bugs should have been worked out long ago. It seems as though Intuit assumes it has a captive audience of customers, and has gotten sloppy and lazy with its software maintenance. Business owners don't have time to fool around with issues like this or to go back to entering each transaction manually. How do we QUICKLY fix this?
