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.
Thank you, this got me to resolve it. No amount of refreshing and closing tabs worked, so I did have to delete my site data after all. Lost my settings, but at least it works again.
