For some reason my Bank of America accounts stopped connecting a week or so ago. Today I tried to reconnect, and after reauthorizing, Quicken downloaded transactions 1,000+ transactions across several accounts and ended up changing the opening balance on one of them that was many 000's too high.
Accounts are set up NOT to automatically download. After the download there are no transactions visible for review and acceptance, and none of the newer transactions from the last 2 weeks are present for review and acceptance.
I have gone through this several times with a backup file from earlier today, and the same thing happens each time.
