When I select the Approve Time function the window will not open

This can be caused by the piled-up cache in your regular browser, @moonlightandsuns. 

Let’s isolate this issue by clearing your browser’s cache. Try using a private browser when you use the approve time feature. If it works, proceed and clear the cache in the one that you're currently using.

Here’s how to go incognito or use a private browser:

• For Chrome, press Ctrl + Shift + N.
• For Internet Explorer or Firefox, press Ctrl + Shift + P.
• For Safari, hold down Command + Shift + N.

Here's the clearing temporary internet files and cache article for detailed instructions. 

You can also use other browsers like Chrome, Safari, Edge and the like if the steps above didn’t work.

Stay in touch if you need further assistance when using the approve time feature. I’m always glad to help in any way I can.
