I appreciate you for getting back to me, lovemore.julie.

There are instances that an issue like this occurs when the system is experiencing a browser-related concern.

We can fix this by running some troubleshooting steps. To start with, let's open QuickBooks in a private window. It is the best place to identify any browser issues. You can use these keyboard shortcuts to open one:

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

If you're able to see Action the button, we can go back to a regular browser and clear its cache. A piled cache can also be the reason for some unexpected behavior on the opened pages. 

We can also switch to a different browser like Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge.
