Quicken Classic Deluxe for Mac Version 8.3.3 (Build 803.58927.100) on a 2020 Macbook Air M1 running MacOS Tahoe 26.2
The first PNC update following the chaos after their website change last month gave me several duplicate transactions and an incorrect PNC checking balance. I manually deleted the duplicates but never found the source of incorrect balance and ended up doing a reconcile adjustment, chalking the incorrect balance up to the other issues, hoping it would be a one time occurrence. I have done numerous updates since then with no issues but today after the update I noticed that once again the Quicken balance was incorrect. I also discovered a group of old transactions, old as in 2014, that were no longer marked cleared or reconciled. Here are my notes:
On 12/21/25 the balance on PNC website and my spreadsheet register (yes, I keep a manual checkbook register!) were in agreement at 11,043.95 but Quicken showed 12,176.73, difference of (1,132.78), I don't know exactly when difference showed up but it was within the past week.
Also discovered a group of uncleared transactions from 2014 totaling 1,132.76 (there was a .02 interest payment in the group), see screenshot WITH THE AMOUNTS BEING SO CLOSE I ASSUME THERE'S A RELATIONSHIP BUT MARKING THESE TRANSACTIONS AS CLEARED, THEN RECONCILED, MADE NO CHANGE TO BALANCE
I sent the info to Quicken via the Report a Problem tab in the app and will follow up here if I get pertinent info.
