Hi, we’ve recently integrated Amplitude Analytics for our Android app, and we did not enabled it on prod yet.
I encountered the problem on our dev project. Some of the user properties that should be tracked automatically are missing, screenshot are below:

For every events Family, OS is also missing:

Versions of Amplitude libs used in the project:
amplitude = "com.amplitude:analytics-android:1.5.2"amplitudeAbTest = "com.amplitude:experiment-android-client:1.8.0"amplitudeConnector = "com.amplitude:analytics-connector:1.0.0"
