I'm really struggling and have been for several months because of this issue of duplicate Chase bank transactions yet to be reviewed. I've lost hours of time hunting down duplicates, because sometimes two different transactions DO have all of the same details, and I can't just exclude one of two transactions because the amounts match.
I switched to QBO from Xero on my bookkeeper's advice, but without a solution to this issue of duplicates I'm definitely dropping QBO. Blows my mind that this issue hasn't been fixed.
