SSO automatically chooses login account with Smart View

Summary:

Until today when I clicked on SSO to sign on to Smart View, I was prompted to choose an account, now Smart View automatically chooses my work account which is not valid with my client

When I log on to FCC on the web using the SSO button, I am prompted to choose between my work email or my client email (or add a different account) and then be prompted for MFA confirmation. This is the same thing that happened when logging in to smart view. Today, when I try to log in to smart view I no longer have a choice of what acccount to use after clicking on the SSO login option. My work email is automatically chosen (which isn't a valid account for this client).
