Log in in error message for Salesforce mobil app

I have an issue logging into Salesforce mobil app.  All the credentials are correct.  I receive a verification code through text, but when I type it in, I get an error message: Invalid or expired verification code.  Try again. I use the code sent to me immediately, so I know it is not expired.  I also double check the numbers.  

The app has worked about two weeks ago.  Now I cannot login to it.
