Let's figure out why the New tab is not working on your end.
We'll check if this has something to do with the browser you use. Browsers have caches that temporarily save your browsing data. When it's full, you could experience unusual behaviors in QuickBooks like non-loading pages, unresponsive buttons. Below are some of the keyboard shortcuts that you can follow:
Google Chrome: Ctrl + Shift + N
Mozilla Firefox: Ctrl + Shift + P
Safari: Command + Shift + N
Microsoft Edge: Ctrl + Shift + P
When you're on the incognito page, click the Newtab again to make sure it's working. If it does, you may want to clear the browsing history of your regular web browser. This will remove previously-stored browsing data that might have caused the issue. Otherwise, you can try using other supported browsers to be thorough.
Hope you’re doing great. I wanted to see how everything is going about the New tab that's not working. Was it resolved? Do you need any additional help or clarification? If you do, just let me know. I’d be happy to help you at any time.
Looking forward to your reply. Have a pleasant day ahead!
