I have same experience. The "Add for Review" button worked during last review, but doesn't seem to be working now. Nothing happens after clicking it. There is consistently a 404 in browser console; not sure if it is related to this behavior. f55965a9.530f9ffe.js:1 GET https://appstoreconnect.apple.com/partials/app-store/js/date-fns-locale-de-index-js.26565ebc.js net::ERR_ABORTED 404
