A browser that ran TREK before 5.1.1 keeps that version's app in its service worker. When the app opened /native-handoff, the worker answered it from its cache with an app that has no such page, which sent the user to /, and the sign-in ended on the dashboard in the browser instead of in the app. The app now opens /api/auth/native/start, which every TREK service worker passes to the server. That page takes the workers off the browser and forwards to the handoff page. Until the sign-in is handed back, the web app registers no service worker and does not reload for a new version: a tab still open on the older TREK keeps its worker alive, and a registration or a reload in the middle of the sign-in brought it back to answer the next page.
