Hi, I'm trying to reduce the space occupied by my app, and I was thinking of enabling the "Release" minification (which if I'm not mistaken uses Proguard) in the "Publishing settings" section in the "Android Player Settings" section.
I've tested the app on a test device and I'm showing test ads (so everything seems to be fine). But I remember reading things about editing a custom Proguard file. However, perhaps over time you have inserted an automatic system that modifies it, I don't know.
So the question is: using minification, do I have to add lines to a Proguard file, or does your plugin do it directly?
If so, what are the red flags that would make me realize that there is a problem with minification?
I am currently using Google Mobile Ads Unity Plugin version 5.4.0, hoping to be able to update it to 6.1.0 when they release it.
