I recently updated my unity from 2019.2.5f1 to 2019.3.2f1. The thing is that the older version had android module that takes 1.1 GB installed but the update doesn’t have it, So my question is do i have to re-download android module(1Gb) every time i update my unity? i will run out of space like this.
Yes, you need to install it again for each version of Unity.
