Not sure when this started happen, but I first saw this today, 20170808.
When I click on an app in iTunes Connect, all I get is the "Ratings and Reviews" page for that app. I can't access the normal pages where you add versions, screenshots, handle TestFlight or anything else. Is iTunes Connect bugged?
The links from My apps look like this: http s://itunesconnect.apple.com/WebObjects/iTunesConnect.woa/ra/ng/app/##########/ios/ratingsResponses
