Other Questions

I'm glad you made it here, pierrel.

Let’s check to see if the browser in your computer has a full cache. This can often cause unusual behavior in the product. To start with, let's open QuickBooks in a private or incognito window.

Feel free to use the following keyboard shortcuts for your reference:

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

If you're able to see the Add lines option from your Purchase Order, you'll want to go back to the regular browser. Then, clear the cache to start fresh. 

Please see screenshot below to see how it would look like:

Otherwise, I recommend using other supported browser to better isolate this behavior.

Be sure to get back to me if you have other questions. I want to make sure everything's taken care of. Take care and have a good one.
