My current Principal 401k account is not able to connect, states "the bank is not available right now." I found a discussion that stated to connect to Principal financial group. The instructions said to first mark the current "not working" account to manual updates first. Then connect to Principal financial group, and during the connection step, after entering credentials, to link the account to the existing "not working" account. When I select the dropdown list, the not working account is not in the list. I can connect the new account fine but I end up with two 401k's. I don't want to delete the existing account and lose the history. Not sure where to go from here. I don't see a way to link account after connecting to Principal financial group. Please help.
