Chase Migration = Account MESS!!
I, Iike many others, had difficulty with (supposed to be) seamless migration to the new Chase data provider. I stopped before I got duplicate accounts and then manually synced my two Chase credit card accounts. It downloads 60 days of transactions? What? Once downloaded I had to manually delete every transaction that was already in quicken from previous syncs/reconciles.
Then the fun began - and I haven't totally figured it out yet. One account is now 1087.56 out of balance and the other was 76.79 out of balance. I reconcile weekly at minimum, thankfully I have a good backup from two days ago.
Be warned!!! Migration is NOT ready for public use!
