I'm connected to Fidelity Investments as Direct Connect. One account is a 401(k) via NetBenefits. Quicken does download transactions for this account, but starting this year there's a problem: it is consistently changing the number of shares purchased in transactions to the wrong amount. What happens is this:
Every two weeks on Friday, there's a 401(k) contribution, which is always for the same dollar amount.
On Saturday I can see the transaction in Fidelity, but it doesn't yet sync to Quicken. I manually enter the transaction, buying the correct number of shares for a security.
Two weeks later, there's another contribution. I update the accounts, and it updates the previous transaction (the one two weeks ago) with the number of shares purchased by this week's transaction. So I have to go back and correct the previous contribution AND manually enter this week's.
I suspect this started happening this year because the company changed to a biweekly payroll schedule; before it was semimonthly, so the contributions were more than 14 days apart.
