Split Application Binary, but 52mb?

Originally my apk size was 59mb, so I turned on that option, now generated 52mb apk and 6mb main.obb

and google play store says no more 50mb apk can be uploaded.

What now? How manipulate apk become below 50mb?

What is in your first scene? If you have a “Big” first scene you will not get below 50mb.
Maybe you need to make a loader scene for that case.

Thx, yes I have only 1 scene and it is over 50mb.
