Hi!

It looks like you have only one scene in the game - you need to have bootstrap scene 0 which loads App scene to have App scene in obb.
See more info at Unity - Manual: APK expansion files

APK - Consists of the executables (Java and native), plug-ins, scripts, and the data for the first Scene (with the index 0).
