Hi Jenny,
Thank you for reaching out to us. I would like to clarify that this is by design. Once the freelancer has submitted work for the milestone and requested pay, the button will say Review & Pay. The "Pay Now" option is only available before the freelancer submits work for the milestone and gives the client the ability to release a payment anyways.
Hi Jenny,
Yes, the funds will be released to the freelancer automatically 14 days after they requested payment if you take no action. That said, once you click on Review & Pay button you should see this page. You should see the options to approve milestone before 14 day’s period ends or request changes.
Could you please check if you’re using a supported browser version and don’t have any plugins installed that would be blocking that pop up? You can find more information in this help article.
Hi Nikola,
So, I have pop-ups enabled on the upwork website, but it still is taking me to a blank page that says "back to overview." I don't get routed to the page where you can pay the actual milestone. Here's what I see. 
Hi Jenny,
I tried but wasn’t able to replicate the issue you’re describing. I was able to see the option to Approve & Pay for that particular milestone here. Could you please try using a different browser or the incognito mode of your current browser? You may also try clearing your browser’s cache and cookies. Let us know if the issue persists and we'll look further into that for you. Looking forward to your confirmation.
