I wouldn't have seen this until now because I didn't have any funds going to brokeragelink since the update until the new year. Fidelity has a sub account for brokeragelink that you can invest outside of your 401k funds. Before the change to fidelity last year, money going to brokeragelink didn't go into the 401k showed as a deposit to the brokeragelink account.
I won't know until tomorrow or Monday if the auto purchase transactions show up in brokeragelink, but today, I see a purchase of "unidentified security" in my main 401k for the amount that should have gone into the brokeragelink account. This never happened and if it continue, I will see double with amounts in 401k that are also in the brokeragelink account.
I am not sure how else to describe this, but Fidelity should understand how these netbenefits account should work (and worked with the old connection mechanism). Happy to answer other question or submit what you need for more troubleshooting.
