Answer 1

Had a similar issue where it was only happening in android 5(lollipop) and below. Turns out my app was partially signed. Running jarsigner -verify -verbose -certs android/app/prod/release/app-prod-release.apk gave jar is unsigned. Turns out the issue was I was not checking the checkboxes for V1 and V2 at the bottom of the 2nd Generate signed APK dialog box. I was leaving out V1. Be keen to chek both.
