Unable to locate idp metadata xml for new SAML application

I’ve just signed up and created a new SAML application. I do not see the setup instructions on the Sign On tab as detailed in all the instructions I’ve seen. In fact the tabs generally look somewhat different. Has the site changed recently, and if so, how do I now get hold of the idp metadata xml?

I have found the answer:

If you are using the developer dashboard you will first need to switch to the Classic UI. If you see a < > Developer prompt in the top left, click it and select Classic UI to switch to the Classic UI.

so do you know why no metadata link on developer console?
