No longer needed. It’s now part of installer packages. When all assets are installed it will automatically request installing main game apk, which is packaged inside installers. Made this change because a lot of people kept installing it without assets or installed assets without it, so now they can’t. If you still have old installers but don’t have main apk - download any of the new installers, run old ones first and then run new one - it will install main apk. Or just download new ones.
