Here it is, 2023 and this still isn't fixed. After several months of successful reconcilations, I too had to unreconcile and make a correction. And, although the balance is correct in money line, I could not reconcile again. After tearing my hair out thinking I was doing something wrong, I unreconciled every transaction, reconciled them all back, changed the beginning balance to the actual beginning balance and I was able to reconcile. It seems that if you go back and change a transaction that has already been reconciled, you'll never be able to reconcile again. I'd love to know how the system is calculating reconciled transactions from one period to the next. Is it including the transaction that I unreconciled, then reconciled as reconciled only? I can't figure it out. So, I too have stopped using the reconcile function.
