Quicken leaves a lot to be desired when identifying downloaded transactions. I spend a lot of time matching up or correcting the accounts Quicken detects erroneously on the downloads.
Also, I just spent a half-hour on the phone with USAA because one of my USAA accounts showed a $59.88 transaction on 26 June that was only identified as "Paypal Transaction." My Paypal account didn't show any such transaction and Paypal's CSR said there were no matching transactions visible to them either. I had to file a dispute with USAA. Only a day or two ago was I advised by Quicken that their automatic renewal in the amount of $59.88 failed. All this mess could have been avoided if they'd have identified themselves when trying to renew.
