Android 6 SSL Certificate Error - trust anchor for certification path not found in Commons Android App

I am working on fixing a bug in the Wikimedia Commons Android app

where Android 6 users get this error when trying to login.

Device: Android 6 (API 23) - Wiko Mobile

App version: 6.2.1

The app currently has no network_security_config.xml file.

The error message is:

java.security.cert.CertPathValidatorException: trust anchor for certification path not found

I am trying to fix this for older Android versions.

My questions:

Will adding network_security_config.xml with system and user certificates fix this? Or do I need Conscrypt library? What is the best approach for Android 6 SSL issues?
