im getting the error message "we cannot sign you in right now please try again in a few minutes or contact support for assistance" across multiple devices using the app.

Since you're able to sign in through a browser without any issues, this confirms the trouble is isolated to the app itself. If you're using iOS, please check the App Store for any pending updates, as this often resolves the issue. If the app is up to date, uninstall and reinstall it before attempting to sign in again.

If you're on an Android device, I'd recommend connecting with our QuickBooks Online Live support team directly. They'll be able to investigate the issue further on their end.

In the meantime, you can access your account through a web browser to avoid any interruptions to your workflow while support reviews the issue.

We appreciate your patience on this. Please don't hesitate to drop a reply below if you have any other questions or concerns.

I have tried all of the above several times including switching between mobile and Wi-Fi networks and using different devices I keep getting the same error, it is extremely inconvenient as I do not have a laptop and use the app exclusively for servicing my customers. Tech support had no insight or help to give me besides creating a ticket which told me that the next update would be in a week from now.
