Facing same issue https://developer.apple.com/forums/thread/708170

Did you figure out a solution @cloudjanak?

Can anyone from Apple staff please give this importance and assist. @eskimo

I have a hybrid app and facing the same issue. App works everywhere -> TestFlight & Simulator, both across iPhones and iPads. But Apple review keeps rejecting saying the content (webview doesn't load). The app loads fine, but the webview doesn't so they are seeing blank screen
