Quicken Classic brought this to my attention yesterday when auto-reconciled failed. I noticed that the downloaded current balance was -$158.10 wrong in both Quicken Classic and Quicken Simplifi. Both used the same OAuth connection. I verified at the bank site the current and available balances and they concurred with what I calculated. So I waited until this morning.
This morning the downloaded current balance is -$188.10 off, which is exactly the same as the pending transactions so the bank is downloading today the Available Balance and not the Current balance. At the bank site today, it shows the Current balance and the Available balance as the same! But this is incorrect. They differ by $188.10, and when I look at the view at the bank site where it shows the running current balance, my calculations are verified.
Of course, I could change Simplifi to show the Available Balance instead of calculating pending, but 1) I don't think this is what my bank intended to do and 2) it would NOT fix Quicken Classic since it actually tallies the transactions.
I am pretty sure that fusb.com uses Netteller as its online banking provider so there could be other small banks doing this starting yesterday as well. I have notified the local bank, but can tell you from experience that they won't have a clue.
