There was a very short period with a bad deploy of the PWA a couple days ago (not native apps) where it would show a blank screen. However your device should auto update once you close ALL vger.app tabs and reopen 2x (once refresh to fetch latest updates, one to reflect on page) -- I checked on my device.
If that doesn't fix it, can you please check your browser console if you're technically inclined? You could try this browser extension or, the official but more complex method
And if you dont want to do that, you can always try deleting site data for vger.app. That will clear your settings and login though.
