I've been using Microsoft Authenticator on my Samsung phone for over a year. At work they're introducing MFA. We're going to be using Microsoft Authenticator. I thought I'd be OK, since I already have the app installed. However, there appears to be a problem. All of the services I would use with Microsoft Authenticator are dimmed out in Microsoft Authenticator. They have a gray background and are disabled. I cannot do anything with them.
Why is that? What can I do to actually use them in Microsoft Authenticator?
