The "Apple Card" is a special sort of credit card. Apple has provided a method for importing card transactions into Quicken. From the iPhone Wallet app, a monthly statement can be exported in .qfx format. The exported file can be transported to a Windows computer by instant message or email. From there, the file can be imported from Quicken's File|Import menu.
Unfortunately, that last step fails with "Quicken is unable to complete your request.[OL-221-A]". At the bottom of the error dialog is a further expression "[OL-221-B]".
A quick Google search yielded lots of similar complaints, but no solutions. Any suggestions?
