Downloading duplicate transactions, only partially SOLVED
This problem, with 2 of my Chase accounts and my Discover account, has been driving me nuts for about a month. Today, I stumbled onto the solution, so I'll share it here.
Basically, after these institutions switched to express web connect, the ID numbers on their downloaded transactions changed. You can see those numbers by turning them on settings/register columns/downloaded ID for the register for the account in question.
If these numbers are totally different, you have the same problem I did.
Here's what to do:
1. Accept the downloaded transaction if that's not automatic for you.
2. Mark the new (downloaded) transaction as cleared or reconciled to match the status of the original transaction
3. Delete the ORIGINAL transaction
You are done. Except.
While implementing this fix on my checking account I learned that several of the repeated downloads applied to QuickPay transactions. I also learned that QuickPay transactions can't be changed without cancelling the transaction. Since these transactions were successfully done in the past, I suspect that cancelling them would be impossible. But I will try and get back to you with a further comment.
This problem/solution also applies (I think) to Quicken for Mac, as it is caused by the institution changing the format of the downloaded ID. This solution came to me while trying to report the problem to Quicken by phone. I had been deleting the downloaded transactions, only to get them downloaded again.
