Hi fileitstaff,
This error message you're encountering typically shows up if the login details entered are not accurate or if the person trying to access MYOB Teams is an approving manager. For a better understanding, you might want to look at the 'Installing and Signing In' section of our 'Using the MYOB Team Mobile App' help page.
If the issue persists, make sure to reach out to our support team directly. You can reach them on Live Chat via our virtual assistant, MOCA, or by submitting a support case via http://myaccount.myob.com/.
Regards,
Earl
