I had a problem updating my Fidelity Net Benefits. Upon troubleshooting I deactivated downloading transactions. When I tried to reactivate it, I got an error message of "UNKNOWN INSTITUTION". I tried another institution and received the same message. I tried to create different types of accounts with different institutions, and received the same error message. The list of institutions always shows up, but accompanied by the error message. All other accounts update fine, but I have not touched them.
