I recognize the urgency in getting this resolved, user57. Let me ensure you'll get the best help available so this gets sorted out.
Since I'm unable to gather sensitive information on a public platform such as the Community for security reasons, and the issue persists after performing the troubleshooting steps my colleague had posted from the other thread, I suggest contacting our Customer Care Team. They have the necessary tools to take a closer look at what's causing this behavior and guide you with further steps to ensure you'll able to receive these SMS codes.
Here's how to reach them:
- Sign in to your QuickBooks Online company and click the Help (?) menu.
- Choose either Assistant or Talk to Human to get started.
- Search Contact Us.
- Start a chat with a support expert.
You can check out our support hours to ensure you get hold of our representatives on time.
Furthermore, I've included this reference that'll allow you to manage security settings and keep your account information up-to-date: Account Management in QuickBooks Online.
Let us know how things worked for you, user57. If you require additional assistance with any other area, please don't hesitate to reply in the comments below. We'll be around to help you further. Have a good one!
