Android app shows white screen - how to debug

I built a mobile app and I was able to deploy it to a remote server and the android app was working. I made some changes and now the app only shows a white screen on launch.

I enabled remote debugging as described (https://developers.google.com/web/tools/chrome-devtools/remote-debugging/#remote-debugging-on-android-with-chrome-devtools).

I can connect to Chrome on my phone but I should also see any apps that use WebView. I don’t see my app. I can open the website for the app in Chrome and see it in the debugger and it loads fine. It’s just the app/apk doesn’t load and I don’t see it in the debugger.

What am I missing?

Also, it launches fine when I do

meteor run android-device
