Cant install while-labeled copy of android app side by side with official

[xklonx]

I changed APPLICATION_ID, put my own google-services.json, then built master by gradlew bundleOfficialPlayRelease,
uploaded it to play store, downloaded apk, tried to install - application not installed.
Uninstalled official app - successfull install. Trying to install back official app - application not installed.
What im missing?

• Plug your device
• Run adb logcat
• Install the app and check the error

Looks like i need to change android:sharedUserId in official/androidmanifest.xml

INSTALL_FAILED_SHARED_USER_INCOMPATIBLE is the error you're looking for.
You did something wrong on your android:sharedUserId on manifests.
