I found this tweet from August 2016.
Is Freedome-Team still working on a Universal App for Windows 10 devices?
Quick update from Freedome side: Microsoft fixed the VPN API in the operating system with Windows 10 Creators Update and we’re continuing with the universal app development.
Good to hear, thanks for your quick response!
Is there a release date or any beta testing programs coming?
There is no timeframe yet but we're working on it, Vetraci.
