Android Packing Issue

I’m having an issue with building an Android APK final package. When I launch the game on my Galaxy S7 the app runs fine, no issues, then I bake the project to Android packaging ETC2, uninstall the Unreal Launch version and drop the APK on my phone, install it, all the assets and lighting disappear. The initial main menu screen loads but all the other assets and the lighting in the game are gone/blacked out. I’ve done this several times, even on my Alpha version in the Google Play store when I download it, does the same thing. I also tested it on an LG Android device as well. It seems the issue may be in the Android packaging compiler? Is there known issues with the Android compiler? Or is there a checkbox, work around or something I’m missing when I’m baking the final project. Any leads will greatly help! Thanks!
