After pressing "See Current Secret" the page ask you for your password for security reasons. So I write it and press "Submit" and it just keeps there processing something. No message errors you just get an endless circle rotating in the "Submit" button and that's it. So I can't get the App Secret.
I always enter to the developer page using my Facebook account so I suposse the password I have to enter is my Facebook one, isn`t it?
Same issue here, 3 weeks later. We have an app in alpha testing and wanted to upload a new build. However, in the time since our first submit (Dec) a new rule has been implemented that >200mb apk's can only be uploaded via a CLI tool. The CLI tool needs the secret key, and the interface to view the secret key is totally borked as OP says. So we're totally stuck without a way to push updates.
