Help! Blank screen on TestFlight

Hi, I built an iOS app from my live website using Median. The app loads perfectly in the Median simulator/preview, and the website works flawlessly in mobile Safari. However, when I install the build via TestFlight on a real iPhone, it launches to a completely blank white screen every time, on cold launch.


The page has a static HTML loading screen that appears before any JavaScript runs. On the device I see pure white, meaning the page does not appear to load at all in the WebView.
It works in: mobile Safari, desktop browsers, and the Median preview.
It fails only in: the installed app on a real device (TestFlight).
Connection is online; pull-to-refresh does nothing.
Offline/caching is disabled in my Median settings.
Could you check the device-side logs for my build and advise what is blocking the WebView from loading the URL on a real device?


Thanks,
