  1. Resolution Note (2020.1.X):

    This particular case has been investigated thoroughly and we have decided, in the interests of protecting the stability and features of Unity for users that rely upon the affected versions, to not address this fix for the time being. We understand that this will cause problems for some users, and so may address in a future version.

    My issue is that UI masks don't work on the iPhone 5C using LWRP

    I'm using this open-source alternative until this is fixed
