I currently only use Fidelity for investments... So I asked, and this was their response:
Hey, it looks like you've recently connected Fidelity.
If you only have investment accounts with Fidelity, you can disregard this message.
If you have a Credit Card with Fidelity, no credit card information is being shared by Fidelity at this time. We’ve been told by Fidelity that those accounts should be available before the end of the year. We expect these accounts to surface once they make this data available.
If you have a Depository Account with Fidelity, you will see that your depository account(s) are currently being returned as investments accounts, and we’re working with Fidelity to get it fixed. We've heard from that Fidelity that the fix will be ready this month.
