Thank you for posting here in the Community, @karlssonservices.
I've checked here and haven't found any ongoing investigations about not being able to log in via the app. Since you already tried updating to the latest version, I recommend deleting and reinstalling the program.
By doing so, we'll be able to check if you'll be able to access your account without any issue. If the problem persists, it would be necessary to look over your app to determine the exact reason.
Since this is a public forum, I suggest contacting the QuickBooks Self-Employed Team, who can pull up your account in a secure environment and utilize specialized tools to review the cause of the login trouble. You can find their contact information at the following link:

Stay in touch whenever you have additional questions about the app. I’m here to make sure you’re taken care of. Have a great rest of the day.
