Im having this problem also.  Bank balance in QB is correct and matches actual bank balance. both are updated, and both match.  the problem is the associated transactions from bank account aren't showing in quickbooks.  ive re-entered bank information multiple times and have clicked update literally 100 times, and i cant get any transations over to qb past about 3 weeks ago.  quick books is showing "updated moments ago".  But there are a few hundred transactions from the last 3 weeks that aren't showing.  the bank balances are current and correct, so there is obviously some sort of a connection, but updating doesn't work to get transations pulled over..
