For many months now, my six Synchrony accounts frequently debit the wrong account when updating. I have to monitor this and manually correct them for every download. For example, I find a debit in the Harbor Freight account that should have come from my checking account [Chase XXX] (always) but instead is shown as [Sam's Mastercard] or another Synchrony account. It seems to happen randomly with all six accounts. I have only one sign-in to Synchrony Bank online, and it shows me all six accounts. I have not been able to establish separate sign-ons for each Synchrony account (and I really don't want to).
I am running Quicken Classic Business & Personal R60.20, Build 27.1.60.20 on Windows 11 Home.
