Ionic-wkwebview: Android build doesn't load any local templates

Hi, I am in the process of migrating my v1 app to wkwebview from UIWebView. Now that apple has officially stuck a deprecated sign on UIWebView, I decided to act.

So far, iOS works well.

On Android, it builds fine but when I deploy to a device, it can’t seem to load any local templates. I’m probably missing something simple. Any thoughts? (removing ionic-webview before building android works just fine)

Android Device OS: 7.0

My allow-navigation :
