I'm still seeing the same error as before. My colleagues open the /activation_ds link and the page is just white with a spinner. The browser log says [HTTP/1.1 401] GET https://appstoreconnect.apple.com/olympus/v1/termsOfService and: Failed to load https://appleid.cdn-apple.com/dist/createService.min.js. A ServiceWorker passed a promise to FetchEvent.respondWith() that resolved with non-Response value ‘undefined’. at service-worker.js:1:2176 I have opened a feedback assistant issue: 22588575

My colleagues are also facing the exact same issue. It looks like the browser after they click "Accept Invitation" takes them to https://appstoreconnect.apple.com/activation_ds?key=.... This page is just white with a spinning load icon. The browser network log shows that a GET call to https://appstoreconnect.apple.com/olympus/v1/termsOfService fails with a 401 error. See attached screenshot.
