Mobile Login Not Working

My Clef login is working fine via a desktop browser, but not when I try to login via a mobile browser.

When I try to login, I click the “Log in with Clef” button. This opens the Clef app, where I enter my PIN.

When I enter my PIN, I see a message at the bottom that says:

“You need to add your first name to your profile to…”

I don’t see anywhere I can do that?

Thanks for your help.
