Guten tag!
I encountered this error when I try to release to Android. In my case, I tried to build app-release.apk from Build > Generate Signed APK on Android Studio.
On this way, it works perfectly on local. But when I download from Google Play, It was down.
The error said, "Could not get BatchedBridge, make sure your bundle is packaged properly".
As a result, I had to build the signed apk via console.
This is the way.

After you set all as the document, you can build apk by
$ cd android &&./gradlew assembleRelease
If you're using Android device to debug via USB, you can run this command.
$ adb install android/app/build/outputs/apk/app-release.apk
Tschüs!
