You may or may not have noticed that recently Schwab transactions in Investment Accounts are being downloaded with a transaction date that’s one day earlier than it should be.

Yesterday I set down to reconcile my Schwab Bank Account and absolutely could not get it reconciled. Of course the first thing I checked was for any prior period changes to reconciled Accounts and the June 30th reconciliation was still perfect, so that wasn’t the problem. I finally figured out the source of the problem, and it was that the Posting Dates for transaction being downloaded in the checking Account. are also being downloaded a day early.
I look forward to Quicken getting this fixed.
