Happy to hear from you again and share progress, @newbornnoise-gma!

Let's stay positive. I'll give you a hand and ensure you're able to sign in to your account using the mobile app. The error message appears when using a different application aside from QuickBooks Self-Employed (QBSE).

It's important to know you've got the QBSE app and not the QuickBooks Online (QBO) app, as there's a difference between the two mobile systems. Once you've verified that you have the QBSE app, proceed with signing in with your account credentials. If you need to download the QBSE app, here's a link you'll need to use:

QuickBooks Self-Employed for iOS device

QuickBooks Self-Employed for Android phone

If you're getting the same results, I recommend contacting our Care Support team. They got the tools to pull up your account and investigate what's causing this hurdle in a private session. You can click the Assistant from the top bar when using a browser. Then enter "Talk to a human" to get live support.

Let me hear from you in this forum if you have additional concerns about logging in to your account. We'll back you up anytime. Have a nice day.
