BoA recently changed their downloading process, which I was easily able to manage through Quicken. Fortunately, I back up my files before any major changes or new connections. The downloaded file stated it download transactions for the last 5-6 days and the downloaded transactions matched my entered info. However, the current balance swung positive by over $10,000 as some transactions in the past were obviously impacted. I restored my original file, printed BoA transactions through 9/1/25 and reconnected again. The same issue occurred. I check the transactions through 9/1/25 and all were correct. However, I cannot go back through over 10 years of transactions to correct the issue.
Any ideas on how to resolve the issue aside from manual reconciliation?
