When signing into my QB account on the mobile app, I get this Error. "Error: We are unable to sign in to this Company." and can't sign in. Anyone experience this before?

You may be experiencing some data issues, userbanjoboyjohn.

Let's try resetting your application's data to fix this error. You can do that by tapping the Help menu and then selecting Reset App Data.

Afterward, let's try signing into your account again.

I've also added this reference to what we can do with QuickBooks Self-Employed: QuickBooks Self-Employed Overview.

Let me know how this step works on your end. Keep safe!

im having the same problem

Thanks for letting us know about this, @meikorajan,

I have a couple of suggestions that you can try to get the application in working order. First, make sure the app is updated to ensure all critical patches are downloaded.

You can also try uninstalling and reinstalling the QuickBooks Self-Employed application to resolve installation corruptions. It will also help reset the application data so it functions properly.

However, if you're still unable to log in, I recommend reporting this to our Support Team. They will create a ticket for this problem and escalate it to our engineers for thorough review. To get our support, check out this link: Contact QuickBooks Self-Employed Support

In the meantime, access your account temporarily on a supported browser while we're looking into this.

Let me know how it goes, as I want to make sure this is resolved for you. I'm always here to help. Have a nice day!
