Thanks for updating this thread, @spikeselectric. I appreciate you going through the steps provided by my colleagues, and I’ll ensure you can link your purchase order to a bill. 

I’ve replicated your concern and verified it works fine. May I know if you’re able to select the More button at the bottom center of your PO, then Copy? If so, have you received any error messages during the process? This will help me verify if there’s a reported issue specific to your case.

In the meantime, it's possible you’re experiencing a browser issue. That’s why you’re unable to copy a purchase order onto the bill. To fix this, let’s use a private browser to access your QuickBooks account. This doesn't retain cache files, so this helps rule out the possibility of a webpage issue. 

Here are the keyboard shortcuts:

• For Firefox, press Ctrl + Shift + P
• For Chrome, press Ctrl + Shift + N
• For Safari, hold down Command + Shift + N

If this works, you’ll need to clear the browser's cache to avoid experiencing strange behavior. By doing this, it’ll remove the history or built-up cache in your default browser, so you can start with a clean slate. You can also switch to other supported browsers as alternatives.

Additionally, see this article for the updated steps on applying an accepted purchase order to a transaction for your supplier: Add purchase orders to expenses, bills, or cheques in QuickBooks Online. This includes the process of removing a PO from an expense or bill.
