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

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

Did you figure out a solution @cloudjanak?
