Concur Mobile - SSO works for some employees but not others?

[CEL22]

I have a small group of end users that cannot access Concur Mobile with SSO. I had no problem whatsoever - followed the instructions to install, entered email address and then had a screen with 2 options - SSO or Password. Other users are not seeing the SSO option - has anyone experienced this? Any recommendations to offer them a fix? Thank you!

@CEL22 when signing in to the mobile app, the first field users see should ask for either Username, verified email or SSO code. If they enter the SSO code for your company, it should sign them in. Is it possible the users are not on the latest version of the app? Also, they could try clearing the cache for the app.
