Additional Information

Our app does use some Cordova plugins, specifically:

cordova-plugin-calendar cordova-plugin-device cordova-plugin-file cordova-plugin-file-transfer cordova-plugin-inappbrowser cordova-plugin-tv-detect

Our Capacitor config:

{
  "appId": "com.example.blah",
  "appName": "Our App",
  "bundledWebRuntime": false,
  "webDir": "dist",
  "plugins": {
    "SplashScreen": {
      "launchShowDuration": 0
    },
    "CapacitorHttp": {
      "enabled": true
    }
  },
  "server": {
    "androidScheme": "https"
  },
  "cordova": {
  },
  "ios": {
    "appendUserAgent": "ios:application"
  },
  "android": {
    "buildOptions": {
      "signingType": "apksigner"
    }
  }
}

The WKWebView+Capacitor.h header file did exist with Capacitor 5.
