I'm developing an Ionic/Cordova/Angular app in Visual Studio Code targeted for Android API 30. Its MSAL sign-in process has a redirect URI that is set up in Azure, let's say it's myapp://callback. Android 11+ devices won't allow it, throwing a ERR_UNKNOWN_URL_SCHEME error. So, under the impression that I need to use http or https, after I changed myapp://callback to https://localhost/callback, I keep getting ERR_CONNECTION_REFUSED. I've tried intents and permissions in the manifest file, but they don't seem to do anything. I've tried plugins, and I get "plugin not installed" errors, even though they were installed/added. What am I missing?
