StrictMode(30621): A resource was acquired at attached stack trace but never released

Environment:

• Android Studio version: 4.0.1
• Firebase Component: com.google.firebase:firebase-auth-ktx
• Component version: 20.0.3
• compileSdkVersion: 29

Description:

It’s not easy to reproduce. Some have observed it to happen more often when disconnecting from the network.

StrictMode keeps terminating the app with this stacktrace:

This is almost certainly a missing #close() statement in the Auth SDK. I’ve filed b/185793197 for internal tracking
