Just found this in my Principal 'messages' on the principal website when I log in. Looks like this isn't going to work anymore for me. :(
"What do I need to know?
As part of our service agreement with your employer, any third-party aggregators you may currently use to store your retirement account data no longer have access to your Principal-serviced retirement plan account information. This means the information on any third-party system you previously provided your credentials to will no longer be automatically updated."
