react-native-meteor not working on android versions 9.0 and above

[ezrogha]

Hi, I have noticed that react-native-meteor doesn't run on android versions 9.0 and above when the app is run via apk, though it works properly on local(using dev server).
i.e
In my code nothing is executed after this line when using v9.0 and above via apk
Meteor.call('Account.checkEmailVerification', { email }, (err, ok) => {
All other versions execute perfectly.

Note: react-native-meteor works properly on all versions when run in development

Any help will be highly appreciated 🙏🏽

I fixed this by adding android:usesCleartextTraffic="true" to android manifest file. Read more about it here.
It occurs because android versions 9+ don't allow insecure connections in release builds. For my case I was connecting to ws:// which would have also worked if it were wss://
