Unable to sign on to mobile app on tablet (android)


I need support in being able to login to the android mobile app.

I am signing in using "Sign in with Microsoft" and go through Microsoft Authenticator etc. and enter the code I receive.

After this step it says it says a "confirmation e-mail for sign-up" to my email. I am just trying to sign on. I receive an e-mail confirmation to start using smartsheet and when I click on it, it mentions I've already been "confirmed".

Is there any work around or can this be resolved ASAP?
