I have been having the same issue for over a week now and it is clear that the issue is not on the client side, but with QBO using the wrong URL for Lowes Commercial accounts. It is also clear that the "QB support" does not actually work to correct the proble, but continues the promote the irrelevant "fix" of "login in an incognito browser window". the QB support team should review all of the posts regarding this issue, the help offered to correct the problem and understand that they need to actually listen to the user. Very disappointing support.
