Dear All, I am able to create invoice seperately and project seperately, but when i try to link one another, I get an error "Sorry, an unexpected problem occured"

Hello, @srikanth1.

Let's access your QuickBooks Online account using an incognito or private browser. This way, we can isolate this unexpected prompt for possible browser-related.

Here are the shortcut keys that you can use:

• Google Chrome, press CTRL  + Shift + N
• Mozilla Firefox: press CTRL  + Shift + P
• Safari: press Command + Shift + N

If you're able to successfully able to link your invoice to your projects, you can clear the cache of your regular web browsers. Lastly, to check any issues with your browser’s health and its compatibility with QuickBooks Online, you can also use the Browser Health Checkup Tool.

I'm just a post-away if you have other questions about tracking your project-related transactions. I'm always here to help.
