No proxy tab is shown on when I go into settings via the little spanner icon in the top right. I’m using Windows 10 and I have set the manual proxy setting on in the Windows Proxy settings
Hey @gouldrt
Welcome to the community! 
The best thing to do in this scenario is to share an image of what you’re seeing, it’s far easier to see something in front of you rather than trying to work it all out using words alone 
Can you also share the Postman version that you’re using please. 
I am facing same issue unable to see Proxy tab or all required setting. I am using 5.5.5 version Version 5.5.5
