Thanks for reaching out to the Community. I understand how frustrating it can be when none of your business info shows up, but no worries, I'm happy to help you get your info showing again in just a few easy steps.
Let's start by narrowing the situation down a bit. To clarify, have you tried opening QuickBooks using a different browser or the App? If so, are you having the same issue? Knowing key details such as this will help to eliminate some of the causes of your business info not showing.
While I await your reply, let's try some basic troubleshooting steps, such as clearing the cache from your browser. Web browsers collect cache to save time when loading repetitive data and images. These files can often become outdated and corrupted, causing issues like your business info not showing. I've included the links for all supported browsers that contain the steps to clear the cache below.
Once you've cleared the cache, close the web browser and open it back up to see if your business info is showing again.
I look forward to your reply. Please let me know if you have additional questions or concerns. Feel free to reach out to the Community or me at any time. We've got your back. Take care. Chat with you soon!
