Hi there Robert,
Let’s first go over some potential fixes together before I route you to our Live Support team, so you can quickly return to managing your business.
Before we proceed, could you confirm whether you've installed the QuickBooks Self-Employed (QBSE) app on your new device? Please note that the QBSE app is no longer available for download as it has been discontinued. When logging in, are you using a browser on your phone? If so, have you encountered any error messages?
To troubleshoot, you can use a supported browser to access QBSE via this link: Log in with QBSE. If you’re unable to log in successfully, please double-check that you’re entering the correct username and password. If you’ve recently updated your password, ensure you’re using the new one.
Additionally, try to avoid multiple login attempts in a row, as this can temporarily lock your account. If this happens, wait 15 minutes before trying again.
If none of the above steps work, you can reach our Live Support team. They can securely access your account and provide guidance on the next steps.
If you need further assistance, please feel free to drop a post below.
