I just spent several days fixing the reconciliation on 2 of my credit card accounts. Frankly it never occured to me that the beginning balance from several years ago could change and throw off the current reconciliation. I found a post that confirmed that this was the case with Bank of America. Very frustrating. I wasted several days work on a problem that shouldn't have happened at all. Terrible customer service. Quicken should prioritize fixing this problem and notifying customers of the possibility so they don't waste their time.
